Detailed Description

Demonstrates clipped, site-indexed Voronoi cells.

This example builds Voronoi cells from a point set, clips every cell against a convex bounding polygon, and exports the result as tabular CSV with WKT.

Usage: ./voronoi_clipped_cells_example [output.csv]

If output.csv is omitted, a default file voronoi_clipped_cells_output.csv is generated in the current directory.
