Like other user I have problem with Topojson. Converted from As.shp and WGS 84 - 4326 projection. It works only with "equirectangular". Attached the json file.
Thank you for any help
Hi,
After some research, I don’t find any document or blog to explain why you cannot use ‘Mercator’ and ‘Orthographic’ but only ‘Equirectangular’.
For your issue, I would suggest create a support ticket:
