This force-directed network visualizes the relationships between actors, directors, and films, with nodes colored by their type (actor, director, or film) and links weighted by the number of collaborations. The layout uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` forces to position nodes, while user interaction is handled via `d3.drag` to manually reposition them. Node labels are displayed, and hovering highlights the node with a blue stroke. The data is loaded from `data.json` and rendered as an SVG, with markers on links to indicate direction.
