This knowledge graph visualizes the relationships between actors, directors, and films, using labeled, arrowed links to show actions like “Acted in” and “Directed.” It loads data from `data.json` and renders an SVG with D3 v6. The layout is computed by `d3.forceSimulation` with link, charge, collision, and center forces. Nodes are draggable via `d3.drag`, and the view supports zooming and panning through `d3.zoom`. Relationship labels are placed along curved paths using `textPath` elements.
