      [null,null,["上次更新時間:2025-07-26 (世界標準時間)。"],[],["The `isUnbounded()` method, applicable to `Geometry` objects like `MultiPoint`, determines if a geometry is unbounded, returning a Boolean. It takes a `Geometry` object as input and returns `true` if the geometry is unbounded, and `false` otherwise. Examples show creating a `MultiPoint` object and applying `isUnbounded()`, printing the Boolean result, then displaying the geometry. Both JavaScript and Python code are provided.\n"]]
