This 2D companion runs the same Bowyer-Watson Delaunay construction as the 3D version on a plain canvas: click to insert a point and watch the mesh rebuild instantly, drag any point to reshape it live, and toggle the Voronoi dual, hover circumcircles, convex hull and triangle shading from the side panel.

⚙ Under the hood

Incremental Bowyer-Watson triangulation with per-triangle circumcircle tracking, a Voronoi dual built from adjacent circumcentres, and a step-by-step construction replay.
