This example shows a force-directed network graph of an arts organization ecosystem, mapping relationships between main entities and their smaller affiliated groups. Colored circles represent nodes, with size encoding hierarchy level, while connecting lines use matching colors to show organizational links. The simulation uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` forces, plus a `drag` interaction for repositioning nodes. Data from a JavaScript array defines custom distances between linked nodes, with the SVG rendering updating positions on each simulation tick.
