This example shows a force-directed network of Tom Hanks’ film connections, with nodes for actors, directors, and movies, colored by group and linked by “Acted in” or “Directed” relationships. The graph loads JSON data and runs a D3 v6 simulation using `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide`, rendered as SVG circles and lines. Node dragging is enabled via `d3.drag`, and each link includes a marker arrow, though relationship labels are attempted on paths but not fully implemented in the final layout.
