This network visualization displays relationships between movie characters, with each node color-coded and shaped by role: Hero (blue star), Villain (red triangle), Sidekick (green circle), and Mentor (orange square). The example builds a force-directed graph using `d3.forceSimulation` with link, charge, and center forces, rendering nodes as SVG paths via D3’s symbol API. Links are drawn as lines, and labels follow node positions during the simulation. Nodes are draggable using D3’s drag interaction, which restarts the simulation with a higher alpha target for responsive movement.
