For a single point, it returns the point; for collinear points, it returns a line. Otherwise, it returns a polygon, which may be a line segment if degenerate. The method accepts `maxError` and `proj` arguments to control reprojection and coordinate systems, respectively. It is demonstrated using a `MultiLineString` object in both JavaScript and Python, showing how to create it and visualizing the original geometry and its convex hull.\n"]]
