This example shows a force-directed network graph of character interactions from the novel Les Misérables. The visualization displays nodes as unlabeled circles and links as straight lines, with the layout computed dynamically through a physics simulation. Using D3 v6 within a React framework, the code applies `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position the 17 nodes and 14 links. The SVG elements update their coordinates on each simulation tick, though the data only includes a subset of the full character relationships.
