d3-delaunay ​

This is a fast library for computing the Voronoi diagram of a set of two-dimensional points. It is based on Delaunator, a fast library for computing the Delaunay triangulation using sweep algorithms. The Voronoi diagram is constructed by connecting the circumcenters of adjacent triangles in the Delaunay triangulation.

• Voronoi diagrams
