This interactive force-directed graph visualizes character co-appearance relationships from the *Les Misérables* dataset. Nodes represent characters and are colored by their assigned group, while black links connect characters that appear together. The visualization uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to compute physics-based layouts. Nodes and labels are rendered as SVG circles with drag functionality, and a zoom transform is applied via the d3 zoom controller.
