For multi-geometries, it sums the lengths of individual components. The method accepts optional `maxError` and `proj` arguments to define error tolerance and projection units, respectively. By default, length is computed in meters. The example demonstrates how to use `length()` on a polygon object and visualize it in JavaScript and Python environments.\n"]]
