Currently, Redash has limited support for maps. It would be great if we could expand the support for different countries' maps by allowing users to upload GeoJSON files. (The commercial version of Dazdata has already implemented this feature.)

In fact, we don't need the function of uploading geojson files. We only need support for loading map data through URLs.
