This example visualizes an organizational network of arts and social impact organizations, with main nodes (large colored circles) representing umbrella groups and child nodes representing affiliated projects. Force-directed layout in d3.v7, using `forceSimulation`, `forceManyBody`, and `forceLink`, positions nodes based on link distances, while `forceCenter` pulls them toward the canvas center. The SVG rendering shows colored links and node labels. Users can drag nodes via the `drag` interaction, which restarts the simulation. Data is defined procedurally in `data.js` with a palette from `colors.js`.
