A hundred random points relax into a stable Voronoi diagram using Lloyd’s algorithm, with each iteration fading the previous frame on a Canvas. The example runs entirely in the browser via D3 v4’s `d3.voronoi()` for polygon generation and `d3.polygonCentroid` to compute new point positions. The code animates convergence through `setTimeout` recursive calls, drawing point markers and polygon edges with the Canvas 2D API, and uses `getImageData()` to progressively darken old frames. Once points move less than one pixel, the visualization resets with a fresh random distribution.
