A force-directed network chart built with D3 v6 visualizes the relationships between actors, directors, and films in a social network. Nodes represent individuals and films, sized and colored by group, while links depict projects with a relationship type and weight. The layout uses `d3.forceSimulation` with link, charge, collision, and center forces, rendering nodes as SVG circles with labels. Users can drag nodes to reposition them, and hovering highlights a node with a blue border. Data comes from a JSON file containing nodes and links metadata.
