If the aim of having ext.graph support Vega 5 is met, we should have the VisualEditor module exclusively produce Vega 5 graphs. Existing Vega 2 graphs should be able to be converted to Vega 5 syntax seamlessly upon an edit.

Existing Vega 1 graphs should be able to be converted to Vega 2 syntax seamlessly upon an edit.
So anyone editing a page will cause unrelated syntax to be updated? We specifically *don't* want VE doing that.
@Krenair I was talking about a graph edit specifically. If the user opens the graph dialog of a graph made with Vega 1, the tool should automagically convert it to Vega 2.
Of course that's an ideal scenario, and I'll have to investigate on whether this is possible without too much pain
For the current, non-aggregated graphs, the migration is very simple -- place "version":2 at the top, and remove all data. from the fields.
For the future capabilities, if you use facets and other fun features, you will need to use the Vega2 ones, as described in https://github.com/vega/vega/wiki/Upgrading-to-2.0 , or better yet, just read the new transformation docs.
I'm inclined to change this task to scrubbing all instances of vega 1 graphs out right. Any disagreement?
Go ahead. Isn't Vega already in version 3? I belief current priority is providing (template) support for interactive worldmaps on the corona pandemic page.
The number of Vega 1 charts used in projects tends to 0. The conversion does not require development efforts and can be done manually.
The basic task of supporting Vega 2.0 with a visual editor was completed a long time ago.
@Seddon am i right? Can we close this task?
At this point we probably could but this problem opens up again once we start looking migrating away from 2 -> 5
I agree, but I think it will be necessary to make a separate task when we come to this. So this task declined or resolved?
I wrote some code (with tests) that automatically maps graphs from the version 2 spec to 5: https://gerrit.wikimedia.org/r/c/mediawiki/extensions/Graph/ /909761/6/modules/ext.graph.lite/mapSchema.js so hopefully this makes this moot (and we could at some later date add this to VE for run a script to make this migration happen)
