Hello @MaxMerg and thank you for taking into account my solution here:
If you just need to plot multipolygons and choropleths, I thing my solution is going to be OK for you. To get ride of any kind of map, just use basemap_visible=False
In my case, slabs my geoDataFrame:
slabs = gpd.read_file(pathJoin(mainPath, "geoSlabsTriangles.geojson"))
fig = px.choropleth(slabs, # slabs is my
geojson=slabs.geometry,
locations= slabs.index,
basemap_visible=False,
color_continuous_scale="ylgnbu",
color = [1] * slabs.shape[0],
)
