A force-directed graph rendered in SVG displays 410 nodes and 1,217 links from the Les Misérables character co-occurrence dataset. Nodes are colored by group using `d3.schemeCategory10`, based on the number of links each character has. The graph uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to compute layout, while `d3.drag` enables node repositioning and `d3.zoom` supports panning and scaling. Link width reflects connection weight.
