  14. Create a circular buffer around a point.
  15. [heading Description]
  16. This strategy can be used as PointStrategy for the buffer algorithm. It creates a circular buffer around a point. It can be applied for points and multi\u005fpoints, but also for a linestring (if it is degenerate, so consisting of only one point) and for polygons (if it is degenerate). This strategy is only applicable for Cartesian coordinate systems.
