This visualization displays a knowledge graph of Tom Hanks's filmography, connecting actors, directors, and films through directed edges labeled with relationships like "Acted in" and "Directed." It uses a force-directed layout via `d3.forceSimulation` with charge, collision, and center forces to position nodes. The SVG rendering includes custom arrowhead markers, curved link paths with `textPath` labels for relationship types, and zoom/pan controls implemented with `d3.zoom`. Node and link data comes from a local `data.json` file, with node clusters distinguished by color.
