geopandas Polygon / MultiPolygon display error

See original GitHub issue

Polygons in GeoDataFrames and GeoJSON don’t seem to be rendering. If they are MultiPolygon they seem to work as expected.

country_gdf = geopandas.read_file(url)

good catch 👀 ! I’d go ahead and support those type combinations, we’ve seen it doesn’t require a lot of changes.

OK, it seems that the gdf contains merged geometry types (Polygons and MultiPolygons). We supported only one type per source in VL because of how CARTO datasets work.

However, For GeoJSON it’s possible to support mixed Polygon+MultiPolygon, and also Line+Multiline and Point+Multipoint (Multipoint is not supported in VL GeoJSON btw https://github.com/CartoDB/carto-vl/issues/137).

What do you think @VictorVelarde @elenatorro?
