A positive distance expands the geometry, while a negative distance contracts it. The method accepts a `distance` (in meters or projection units), an optional `maxError` for approximation tolerance, and an optional `proj` for specifying the projection. It operates on a `geometry` and returns a new `Geometry` object. Example code is provided in JavaScript and Python using the MultiPoint object to demonstrate the application.\n"]]
