A force-directed knowledge graph maps relationships between actors, directors, and films, with edges representing actions like "Acted in" or "Directed" and node colors indicating entity type. Built with d3.forceSimulation, the visualization applies charge, collision, and centering forces, while links include arrowhead markers and curved path labels showing relationship types. Nodes are draggable, and the entire graph supports zooming and panning via d3.zoom. The SVG rendering pulls data from a local JSON file containing nodes and links with metadata such as relationship value and source/target types.
