A force-directed knowledge graph maps relationships between actors, directors, and films, with arrowed links showing who acted in, directed, or wrote each movie. Node colors and sizes vary by group, while link thickness reflects connection strength. Built with D3 v6, the visualization uses `d3.forceSimulation` for layout, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide` for physics, and SVG markers for arrowheads. Zoom and drag interactions are enabled via `d3.zoom` and `d3.drag`, with relationship labels rendered along curved link paths using `textPath`. Data comes from a local JSON file.
