How are polygons rendered in Azure Maps Web SDK?
The Azure Maps Web SDK converts these Point features into Polygon features. Then, these features are rendered on the map using polygon and line layers as shown in the following code sample. A Shape class wraps a Geometry or Feature and makes it easy to update and maintain these features.
