Polygon layer can display all geometry types defined by RFC 7946 (GeoJSON): Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon.

You can load a GeoJSON file (with a single Feature or a FeatureCollection) or a GeoArrow file.

A path GeoJSON layer can display data like trip routes or contours. Stroke color can be set with a numerical field.

A polygon GeoJSON layer is essentially a choropleth layer and works best for rendering geofences. Fill color or height can be set with a numerical field. For example, it can display population by census tracts.

To add a polygon layer, your dataset must contain geometry data.
