Fork of arrow
This network diagram displays relationships between actors, directors, and films from the provided JSON data, using colors to distinguish grouped node types. Built with D3 v6, it employs `d3.forceSimulation` with link, charge, collision, and center forces to position nodes, which are rendered as SVG circles and draggable. Links are SVG lines with arrowhead markers, and the code attempts to attach relationship labels via `textpath`, though some rendering tasks remain incomplete. The visualization is centered in a 960x600 SVG canvas.
