It accepts optional parameters `maxError`, defining the error tolerance during reprojection, and `proj`, specifying the projection for the operation. If `proj` is not set, operations use a spherical coordinate system. Example usage shows defining a Polygon and a BBox as `inputGeom`, then uniting them using `polygon.union()` method and visualize results.\n"]]
