This network visualizes relationships between six movie characters, using color and shape to encode each character’s role (Hero, Villain, Sidekick, Mentor). The layout is computed by D3’s `forceSimulation`, combining `forceLink` for edges, `forceManyBody` for repulsion, and `forceCenter` for anchoring. Nodes are rendered as SVG paths with distinct D3 symbols (`symbolStar`, `symbolTriangle`, `symbolCircle`, `symbolSquare`), and lines represent character connections. The simulation updates node and link positions dynamically, and supports interactive dragging.
