It takes optional `maxError` and `proj` parameters to control reprojection accuracy and the operation's coordinate system. The `left` geometry is a given one, and the `right` one must be provided. The provided examples demonstrate using `union` on a Point geometry with a BBox geometry in Javascript and Python. The resulting geometry is displayed on a map.\n"]]
