geometry property
The geometry of the vector marker symbol element.
The geometry can be a point, polyline, or polygon. When rendering, the symbol draws according to the shape of the geometry. When setting a geometry, make sure that the corresponding symbol is appropriate for the desired drawing effect. For instance, a polygon geometry would pair best with a MultilayerPolygonSymbol, drawing the symbol with the polygon geometry. The coordinate values defining the geometry are in points. ArcGISExceptionType.commonInvalidArgument Raised when either the vector marker symbol element or geometry parameter is null.
