Organization Graph Diagram
This force-directed organization graph shows the relationships between community arts organizations. Four central colored nodes connect to smaller child nodes, which have tiny unnamed leaves. The SVG visualization uses `d3.forceSimulation` from D3 version 6 with `forceManyBody`, `forceLink`, and `forceCenter` forces, plus `drag` interaction. Node colors and link distances are defined in `data.js`, while circles, lines, and text labels are rendered with D3 selections in the React framework.
