This force-directed graph visualizes character co-occurrence in Victor Hugo’s *Les Misérables*, with a Voronoi overlay added to the classic D3 example. A physical simulation of charged particles and springs positions related characters closer together, while the Voronoi tessellation partitions the space around each node, so that any point in the plane can be associated with the nearest character. This makes it easier to select and drag nodes without having to click directly on them. Each character is drawn as a small circle colored by group, with translucent Voronoi cells and gray links representing co-occurrence strength. The visualization uses d3.v4, renders to SVG, and was forked from Mike Bostock’s Force-Directed Graph. Drag any node to reposition it; the simulation and Voronoi cells update live.
