A field of randomly walking points forms a continuously updating Delaunay triangulation. Each triangle in the mesh contains an inscribed circle, with the circles rendered in a dark color against a light background. The animation runs on an HTML canvas, with the Voronoi and Delaunay calculations handled by the d3-voronoi library, while the points themselves are displaced using a simple random-walk algorithm. The code demonstrates the geometric relationship between the triangular mesh and the inscribed circles, which change as the points drift across the viewport.
