GeoJSON PreviewingWe’ve been rendering GeoJSON files for a while now, but now it’s even easier to preview them if you edit them in the web view. Simply click the “Preview” button while editing to view a live preview of the file as you’ve edited it. If you run into any issues, check out the map help documentation.
