For multi-geometries, it sums the lengths of individual components. It returns a float value. The method accepts optional arguments: `maxError` to specify error tolerance during reprojection and `proj` to define the output coordinate system's units (defaults to meters). The provided code examples demonstrate its application on a `MultiPoint` object in both JavaScript and Python, calculating and printing the length and visualizing the geometry.\n"]]
