Excel .xlsx spreadsheets that automatically generate XML code for .SVG graphics

Click at right to show/hide content re User:RCraig09/Excel to XML for SVG

Transcluded from User:RCraig09/Excel to XML for SVG: General concept above; examples below. Warming stripes (five examples compared) Warming stripes bar chart Bar chart (vertical) Pie chart Line charts Scatterplot I've uploaded .xlsx (Microsoft Excel) spreadsheets that automatically generate XML code for charts in SVG format. You simply paste or enter your data into the spreadsheet, and specify image dimensions, number of grid lines, font sizes, etc. The spreadsheet instantly and automatically generates a column of XML code that you simply copy and paste into a text editor and save as an ".svg" file. The spreadsheets produce lean SVG code, avoiding the "extra stuff" that Inkscape inserts. They should save you time in creating SVG charts. Feedback and suggestions on my talk page are welcome.

Requesting a Wikipedia Logo

Greetings RCraig! May you please consider making a localised Wikipedia logo for Tumbuka language Wikipedia. Unfortunately we don't have our own logo whilst most local wikis do have. The English words "WIKIPEDIA" in Tumbuka translates "WIKIPEDIYA" and the motto "The Free Encyclopedia" translates "Nkhokwe Yavinjelu Yaulele". .

The Tumbuka Wikipedia is available at (tum.wikipedia.org). Thank you. Tumbuka Arch (talk) 15:32, 27 July 2022 (UTC)

@Tumbuka Arch: I suggest you place a request at Commons:Graphic Lab/Illustration workshop. Many more people will see your request. RCraig09 (talk) 20:22, 27 July 2022 (UTC)

own work

Regarding your comment at Wikipedia:Wikipedia:SVG_help, I would like your opinion on a proposal to remove "own work" from the Upload-Wizard. I personally hate wrong {{Own}} claims, since they are difficult to detect and differently to missing source usually don't lead to a deletion.  — Johannes Kalliauer - Talk | Contributions 19:11, 7 April 2023 (UTC)

@JoKalliauer: I understand your frustration. I think that the "Own Work" option should remain, but should be modified:

This file is my own work (and not a copy or derivative of someone else's work)

— RCraig09 (talk) 19:48, 7 April 2023 (UTC)

Thanks !

Hello RCraig, it been 3 years since we worked on raising awareness. Thank so much for your "Lower the curve / Raise the line" series of animations, it was a significant work which did spread understanding and awareness. Likely saved 10s of thousands, likely more. Thank you ! Yug (talk) 09:51, 10 May 2023 (UTC)

@Yug: I don't know if it saved lives, but in any event those GIFs were the result of a successful collaborative effort among several editors. So thanks to you. RCraig09 (talk) 13:33, 10 May 2023 (UTC) (moved from User page RCraig09 (talk) 21:44, 12 May 2023 (UTC))

Did you figure out guidance regarding fonts in thumbnail view?

Thanks for making this: File:20200522 SVG font rendering at different thumbnail sizes.gif, but there's no guidance you offer with respect to it. Looking at one of your more recent images File:202107 Percent of global area at temperature records - Global warming - NOAA.svg, the fonts appear better than I've been able to pull off. Did you figure any guidance out for how to avoid crap looking fonts, or did you create a bug against wikimedia for the issue?

I played around a bit with some svgs, but the fonts seem to be semi-crappy across all sizes, and there's no magical divide between 1.7 and 1.75. I also see that you made your demonstration graphic as a GIF instead of SVG, I guess to show the comparison, but since the complaint is about SVG it makes it hard to see if the issue is still real. A bug could have been fixed, or it could just be that the svg rendering engine decides to switch to a different base font once a font gets to a certain size, where the font size is determined by font size / image width. In that case, there's nothing magical about 1.7 vs 1.75 because it all depends on the base scaled font size.

Thoughts? Do you have an svg that can be used to test the 1.7 vs 1.75 issue? Efbrazil (talk) 19:08, 30 May 2023 (UTC)

Oy, User:Efbrazil, the GIF is ancient history, when I was still using Inkscape, and somewhat amateurishly. I've since vastly simplified my SVGs by starting with a spreadsheet chosen from User:RCraig09/Excel to XML for SVG, and then used a text editor to group all my text between

<g font-size="40px" font-family="Liberation Sans,sans-serif" text-anchor="middle" fill="black">

and

</g>.

My files have generally a fraction the byte count of Inkscape files (see how lean the code is for File:2000- Clean power installation - wind, solar, storage - US.svg).

Even so, there are ongoing SVG font rendering problems on Wikimedia, which seem to involve (can't be sure) <tspan> elements; and sometimes needing to include specifications in particular <text> elements rather than depending on inheriting them from a group <g> specification. (Recent details are shown here at Help:SVG.)

I've never seen a repetition of the upright=1.7 vs 1.75 issue, probably because I've mostly avoided Inkscape and gone to lean code. If you want to see an old kluge, though, you could experiment with older versions of File:20200508 New Zealand government structure.svg, which is the basis of the GIF. RCraig09 (talk) 19:36, 30 May 2023 (UTC)

Ah, the graphic was featured on the svg help common problems area which is how I stumbled on it. It read like it was part of a help topic. I just deleted the graphic from there so it won't cause other people confusion:

https://en.wikipedia.org/w/index.php?title=Wikipedia:SVG_help&diff=1157780134&oldid=1157775976

Funny you are currently editing that page further down, I hadn't seen that.

What I always want to do is match as closely as possible the text on wikipedia pages themselves.

One thing I was wondering about is whether it would help to have a preferred width for graphics. Right now I'm popping them out at a width of 960, but there's no real rhyme or reason to that number. At that width, a font-size of 37 renders to approximate the size of text on the wikipedia page. Do you have a preferred graphic width that you use, and does that help with fonts somehow? Efbrazil (talk) 22:57, 30 May 2023 (UTC)

— @Efbrazil: I don't have a preferred pixel size for diagrams, though based on each graphic's content, my mental default is to choose a 16:9 or 4:3 aspect ratio just in case something is used on-screen. I make it big enough to comfortably fill my Mac desktop screen: usually 1200w:675h or 1000w:750h pixels. I've found there's really no ideal aspect ratio since content is so varied. The size gets scaled within Wikipedia articles anyway.

— I'm planning to replace the GIF at Help:SVG, because it's not true to say it's "no longer relevant" (your edit summary). The problem has not been solved, and so it's an ongoing warning that using small fonts may be the cause of someone's problems. It is indeed part of a help topic. I forget what is the danger zone for which fonts are too tiny, but with 1200w:675h or 1000w:750h I regularly use fonts as small as 30px or so (ideally >40px for substantive text, 50-70px for some chart titles, maybe smaller than 40px for less substantive numbers like years on a horizontal axis). Of course I try to simplify, simplify, simplify any SVG code within smelling distance of text: these RSV text rendering bugs make one superstitious. RCraig09 (talk) 02:48, 31 May 2023 (UTC)

I think keeping the graphic there in the meantime without guidance is just confusing though. What are people supposed to take away as guidance? Not to use 1.7, and instead use 1.75? Please replace it or delete it until you have something better.

What is really needed is prescriptive guidance, telling people how to create text that looks good in thumbnails. I have a system similar to yours. Maybe we should try to offer that guidance to people. How about this:

Fonts should be sized so that they look good as thumbnails on wikipedia pages and so they are easy to view on smartphones, which is how most people access wikipedia. Very few people click images and zoom them in to see them, so avoid using images with fonts that are too small to be legible in thumbnail view.

In order to match text on wikipedia pages, here is guidance that will get you close:

A font family similar to wikipedia that is browser and wikimedia safe is font-family="Liberation Sans,sans-serif"

The font size that appears in a thumbnail is a combination of svg width, thumbnail width, and font size. To match wikipedia font size as a thumbnail, use font-size = (63/(your upright value))*((your svg width)/1000). For instance, if the thumbnail will be scaled up to thumb upright=1.35 and your image has svg width of 960, set font-size in the svg to (63/1.35)*(960/1000) = 44.8. Efbrazil (talk) 17:01, 31 May 2023 (UTC)

— @Efbrazil: I generally like the proposed text you've written. However, I sometimes zoom into/out-of a web page using Command /- or Control /-, which would subvert any specific numerical recommendations you make. I think your description is a bit long, but the formula and examples would be helpful (I haven't verified their accuracy). I suggest starting a section at en.WP's SVG help asking what other experienced editors have found to be a viable size threshold for font sizes, and maybe proposing specific shortened text. Also, I don't know where the description would be added where significant numbers of Graphic Dudes would even notice it.

— Re the GIF: There is (presumably) still a problem with small font size renderings, about which people should be made aware—so they can experiment with larger font sizes as I did. Your write-up might help, with its specifics. If you want to develop prescriptive guidance as you have suggested, that would supplement the warning provided by the GIF. RCraig09 (talk) 17:24, 31 May 2023 (UTC)

Good! I added a new section with most of the text plus your image, focused on font-size instead of font-family. I think it is better than what was there before, although there is room for improvmenet still. Go ahead an add edits as you see fit. Efbrazil (talk) 17:45, 31 May 2023 (UTC)

Problem uploading SVG map (created on Inkscape) to Commons

Hello RCraig, I saw that you are an experienced user in SVG files on WikiCommons and wanted to reach out to ask for help on a map I am trying to upload here. It is a map I made using Inkscape about different proposed subdivisions of my country, Bolivia. The problem I am having is when I use the Commons:Commons SVG Checker, it says "Successfully parsed XML structure" but also "Omited rendering of SVG because the file size limit has been reached", so I can't preview how well the SVG file I want to upload will look. I don't know if I have to first make the file size smaller in order to upload it to Commons or if there is something else I have to do. It is my first time uploading an SVG file, so I'm sort of lost here. Thank you in advance for your time and help. Ruditaly (talk) 13:30, 13 July 2023 (UTC)

@Ruditaly: You could try uploading to File:Test.svg, so that you and others can see your specific file. Also, help may be available at Help talk:SVG or Commons:Village pump. Buena suerte! —RCraig09 (talk) 13:52, 13 July 2023 (UTC)

Thank you very much. I actually have uploaded it to the File:Test.svg site, but for some reason the thumbnail shows my map with a black color, even though the colors on the labels in the top right part of the SVG show without problems. Do you maybe know why that is? Thanks again. Ruditaly (talk) 14:00, 13 July 2023 (UTC)

I'm sorry, I don't understand the problem. However, a 9,000,000 byte file is extremely large for SVG. For this map, I would expect a file size of ~300,000–1,000,000 bytes. Also, the file has 1,079 "paths" (separate elements), which does not seem necessary for the number of districts in Bolivia. I suggest asking experts at Help talk:SVG or Commons:Village pump. —RCraig09 (talk) 14:16, 13 July 2023 (UTC)

@Ruditaly: You could also ask for help at Wikipedia:SVG help on the English-language Wikipedia. RCraig09 (talk) 19:53, 14 July 2023 (UTC)

XLSX files with data for the SVG graphs created by you

Where could we find files with data inserted for all SVG graphs which were created by you from XLSX? In case we want to update the existing graph with the data from the new year? I am personally interested for the graph you did for https://en.wikipedia.org/wiki/Growth_of_photovoltaics . Thanks for interesting work though. Please reply. — User:Sintaj User talk:Sintaj 13:02, 29 October 2023

@Sintaj: Welcome to Wikimedia.

— Exactly which image do you want updated?

— If you want changes to a file I uploaded, it would be easier for me to make changes myself, rather than trying to teach another editor how. Please describe what changes you want.

— It is rare for one editor to change another editor's image. This is because the image may be used in many different Wikipedia articles, and in Wikipedia articles in different languages. If you want to make your own chart, you will have to start with the source data linked at the Wikimedia Commons file description page.

— Separately: when you post to a User Talk page, you should add it to the bottom of the page. That is why I have moved your post down here. RCraig09 (talk) 15:41, 29 October 2023 (UTC)

Warning stripes picture as featured picture candidate in Commons

Hello ! Since you uploaded the picture, would you support my proposal to promote it a featured picture in Commons? Commons:Featured picture candidates/File:20181204 Warming stripes (global, WMO, 1850-2018) - Climate Lab Book (Ed Hawkins).png Effco (talk) 12:24, 4 November 2023 (UTC)

Thank you, @Effco: I have entered my support on the Featured Picture Candidate page. I'm not sure if there is anything more that can be done; is there a need to write a "blurb" to go along with the image when featured? If so, where and how? RCraig09 (talk) 15:49, 4 November 2023 (UTC)

Thank you ! I'm not sure about what a "blurb" is, I'm new to this featuring process :-) Effco (talk) 16:14, 4 November 2023 (UTC)

@Effco: A "blurb" is a short description that goes along with the featured image, so that viewers will better understand its nature and purpose. (See https://www.dictionary.com/browse/blurb .) The "blurb" for Friday's en.WP Picture of the Day (POTD) was really long; I think most are shorter, as you can see from the Commons Main page. However, the warming stripes image would require some explanation, though not nearly as long as the POTD blurb. RCraig09 (talk) 17:20, 4 November 2023 (UTC)

Ok thank you for the explanation. But do we need that blurb now ? — Preceding unsigned comment added by Effco (talk • contribs) 17:23, 4 November 2023 (UTC)

@Effco: I don't know for sure when a blurb is needed. To be safe, I just added a proposed blurb to the nomination page. RCraig09 (talk) 18:42, 4 November 2023 (UTC)

• @Cmglee: ... wishing you #HappyGraphix in 2024! — RCraig09 (talk) 17:56, 31 December 2023 (UTC)

  Thanks, RCraig09, and you too!

  I've just noticed that you use Excel spreadsheets to generate SVG. Using native Excel shapes to form warming stripes is ingenious.

  I've been discussing with TilmannR on generating SVG with JavaScript that replaces itself with static SVG, yet embeds itself as a comment. Doing the avoids the user needing any software except a web browser, which they likely already use to view Wikipedia.

  Might you be interested to explore this technique with us? cmɢʟee ⋅τaʟκ 03:48, 1 January 2024 (UTC)

@Cmglee: Years ago, I had C programming experience, but never Javascript or Python etc., or how to use a browser for this purpose. I think that more people have access to Excel than know how to program in Javascript, even though Excel costs money. :-\ It's not practical for me to learn at this point. RCraig09 (talk) 05:54, 1 January 2024 (UTC)

That's a very fair point. Coming from the other side, I must say I'm a beginner in Excel, just know the basics and simple macro programming. Good luck with your Excel SVG endevour, cmɢʟee ⋅τaʟκ 06:21, 1 January 2024 (UTC)

@Cmglee: Actually, I wrote the Excel spreadsheets using basic arithmetic and text functions, though some cell contents are long and filled with pesky details. Nothing I would call a 'macro' (or serious sequential 'programming') is involved, since the average businessman can learn basic Excel. (Users of the spreadsheets, of course, don't even need to know much about Excel, but can simply paste data into the spreadsheets, enter a few numbers like axis ranges and font sizes, and copy paste a column of text into an svg text file.) RCraig09 (talk) 06:32, 1 January 2024 (UTC)

CC @Timeshifter:

Thanks for explaining. I note that you host your spreadsheets on Google Drive as Commons doesn't allow .xlsx files.

Earlier last year, I collaborated with Timeshifter (talk · contribs) to create a Google Sheets spreadsheet to generate SVG to paste into a template SVG. A problem we faced is that my personal Google account always runs out of quota and the sheet becomes read-only. Your method still works in this case, but the user has to download the sheet to run on their own spreadsheet software. I wonder what a good solution is (besides ensuring my not going over quota!)

I suppose using Toolforge is best, but it's a steep learning curve. Cheers, cmɢʟee ⋅τaʟκ 07:47, 1 January 2024 (UTC)

Is the use of tinypng.com a good idea?

20151202 Ed Hawkins (scientist) at COP21 Paris

I note that the image on the right was "[run] through tinypng.com to reduce file size". Elsewhere you advocate the use of web‑based services to shrink image files. Is this good practice? I normally follow the opposite strategy: upload the 26MP JPEG from my camera and then upload one or more modified versions (cropped, tweaked, softened, sharpened, and so on). At no point do I reduce resolution. The user has the option to download smaller versions by selecting something other than the original version of the latest file. Just curious. Perhaps there is some logic that has escaped me? Best, RobbieIanMorrison (talk) 07:27, 10 June 2024 (UTC)

@RobbieIanMorrison: Tinypng.com and Tinyjpg.com do not reduce image resolution. As I understand it, they abbreviate color codes for each pixel (I think, probably, using three hexadecimal characters per pixel rather than six), so that file size is reduced without noticeably changing the appearance of the image. RCraig09 (talk) 16:13, 10 June 2024 (UTC)

Many thanks for that information. The science of color space remains somewhat of a mystery to me. RobbieIanMorrison (talk) 20:33, 10 June 2024 (UTC)

Small sampling of colors using three hexadecimal characters

@RobbieIanMorrison: No problemo. It's a fascinating area for those of us who are generally "visual thinkers". Mainly, just remember that the numbers, left to right, are red green blue (either rgb or rrggbb depending on 3- or 6-character w:hexadecimal coding), and that larger numbers represent lighter shades (000=black and fff=white). My chart at right gives you the idea, showing 768 of the 4096 colors possible with 3-character codes. (Sorry I don't know the .jpg or .png formats incorporating those color codes into image files.) 02:15, 11 June 2024 (UTC) It's my understanding that Wikimedia favors high resolution images when possible and appropriate (for authenticity and quality of the collection), but also smaller file sizes if possible (to conserve bandwidth). RCraig09 (talk) 02:25, 11 June 2024 (UTC)

@RCraig09: Thanks. I have some experience in numerical software development — so the various sampling choices, encodings, and associated compromises come as no surprise in general terms. Just that I haven't sat down to explore the details. My Sony a6700 camera offers HEIF but I use JPEG for portability. Ditto, I have not explored color spaces, lookup tables, and corrections for videography. For Wikimedia, whenever possible, I upload the highest resolution JEPG base file I can — say 26MP — and then new versions with cropping, color tweaks, and sharpening. That kind of provenance is useful, I believe. But that same image is also offered for download at 320 × 225px or 27KiB. So quite small. Are there downstream downsides for the shrinking processes you are using? I quite often strike color space issues when editing in GIMP, so I always a bit wary of processing that departs from widely used defaults. Best, RobbieIanMorrison (talk) 08:12, 11 June 2024 (UTC)

@RobbieIanMorrison:

— I'm not aware of any genuine downstream software problems caused by using abbreviated color codes. It's my understanding that the only issue might be that the very slight difference between #rgb and #rrggbb might be humanly perceptible with extremely light shades (approaching #fff or #ffffff).

— Separately, 26 MB seems like a huge size, and though smaller PNG versions are available to those who come to the Wikimedia Commons file description page, I'm not sure whether huge originals burden transmission bandwidth when an encyclopedia page is rendered thousands of times a day; that's why I use tinypng/tinyjpg or cloudconvert.com. Also, depending on the subject, I limit image resolution to be no larger than a large desktop display screen—I'm presuming it won't be rendered on a w:Jumbotron :-D RCraig09 (talk) 16:50, 11 June 2024 (UTC)

For for the record, I wrote 26 MP (pixels) which equates about 16 MB (bytes). I am going to do some tests on post‑processing your Ed Hawkins image. And also see what the Wikimedia policies/guidelines are on upload specifications. Wikipedia does not serve full resolution image files on demand unless viewers click thru to inspect that image for a second time — then that image usually renders noticeably slowly and the transfer is substantial. Thumbnails remain thumbnails of course, until clicked upon first time by users. Back in due course! RobbieIanMorrison (talk) 11:04, 12 June 2024 (UTC)

The before and after Ed Hawkins files both reported "sRGB IEC61966-2.1" color space (more on sRGB). Both opened into GIMP with out difficulty in both original and converted GIMP‑native color space. All images looked very similar, aside from the blurring edit on one. So that is encouraging. The relevant Commons policy is COM:IG and discussion is Commons:First steps/Quality and description. Citing the latter "Generally speaking, image quality and resolution should be as high as possible so images can be used in high-quality printouts, for example". The first link recommends a minimum of 2 MP (pixels) while adding "rules can be broken". Having been involved in photography for decades and watched technologies develop and be eclipsed, I favor not throwing away information. Once stored on Wikimedia servers, that base image can be converted and utilized as appropriate. While noting also that AI is set to revolutionize photographic enhancement (and manipulation too of course). Interesting discussion. Best, RobbieIanMorrison (talk) 17:03, 12 June 2024 (UTC)

Labeled x-axis for LCOE plot

Levelized cost of energy

Hi and thanks so much for your beautiful chart on the levelized cost of energy from various technology categories (shown here on the right). I wonder if it would be possible to add a labeled x-axis showing the years to which this refers. Otherwise, it is a bit unclear what the plot refers to. Thanks! Zvika (talk) 11:52, 12 September 2024 (UTC)

@Zvika: Hmmm... I see that the source has updated its data through 2024. It will take me a while to update the chart (it's complicated), and I'll try to remember to make the time axis label more specific. RCraig09 (talk) 12:28, 12 September 2024 (UTC)

@Zvika: Version 7 is uploaded. You may need to Wikipedia:Bypass your cache to see the revised version. RCraig09 (talk) 21:03, 12 September 2024 (UTC)

Thank you! Zvika (talk) 06:55, 13 September 2024 (UTC)

Converted your gif to ogg

Hi, I recently converted your File:20200327 Climate change deniers cherry picking time periods.gif into an ogg video. Did I do any error with the licensing? Do I have your permission for this? And do I need to use the Template:Derivative versions on the original file? Yaqub Qomarudin Dibiazah (talk) 23:37, 7 December 2024 (UTC)

@Yaqub Qomarudin Dibiazah: Thank you for your interest. I have changed the license template on your OGG. I have also added a "Related file" section, because I am not sure about the Template:Derivative versions. Best wishes. RCraig09 (talk) 04:43, 8 December 2024 (UTC)
