This visualization uses a grouped force layout to cluster the character network from *Les Misérables* by community. Draggable nodes are colored by group, with links showing connections, while a Voronoi overlay dynamically partitions the space to visually reinforce each cluster’s territory. The simulation runs on `d3.forceSimulation` with link and charge forces, and custom logic on each tick adjusts node positions toward their group’s centroid. The Voronoi cells, rendered as SVG paths via `d3.voronoi`, update continuously as the layout settles or as users drag nodes.
