To export these maps we first download the simplified shapefile of lands polygons from the OpenStreetMapData page.
Then we project the shapefile to EPSG:4326 coordinates using mapshaper's project feature.
Finally we apply the Douglas-Peucker algorithm with different resolutions using mapshaper's simplify feature.
You can find the source code of the exportation process here.
Below you can find references to all the resolutions available for this kind of map.
