RubyVor provides efficient computation of Voronoi diagrams and Delaunay triangulation for a set of Ruby points. It is intended to function as a complemenet to GeoRuby. These structures can be used to compute a nearest-neighbor graph for a set of points. This graph can in turn be used for proximity-based clustering of the input points.
