A force-directed network diagram maps actors and directors to their films, with nodes colored by group and sized by connection value. Draggable circles represent people and movies, while gray lines show relationships such as "Acted in" or "Directed." The visualization uses D3 v6's `d3.forceSimulation` with link, charge, collision, and center forces, rendering nodes as SVG circles and links as lines with markers. Data comes from a local JSON file, loaded via `d3.json`.
