This interactive force-directed network chart visualizes relationships between actors, directors, and films. The SVG rendering uses `d3.forceSimulation` from D3 v6, with forces for links, many-body repulsion, collision, and centering. Node color groups distinguish entity types, while draggable circles and link markers show connections. The data is loaded from a local JSON file, and the visualization uses `d3.forceLink` and `d3.forceManyBody` for layout.
