This force-directed network chart visualizes the relationships between Tom Hanks, film directors, and the movies they worked on. The D3 v6 code loads JSON data and uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCollide` to position nodes. The SVG render distinguishes node types by color and draws links with markers, though node and link text labels remain unfinished.
