A force-directed graph shows the network of organizations connected to the Kenneth Rainin Foundation, with nodes sized by hierarchy level and colored by their parent organization. D3’s `forceSimulation`, `forceManyBody`, `forceLink`, and `forceCenter` arrange the nodes and links, while drag interaction lets users reposition them. Data is defined in `data.js` using the supplied `colors` palette, and the SVG rendering updates on each tick to reposition circles, lines, and labels.
