A network graph visualizes the relationships among Kenneth Rainin Foundation grantees, with four main organizations connected by colored links and surrounded by child nodes and anonymous leaf nodes. Built with D3 v6, it uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position elements. SVG circles and lines render the structure, with drag interaction allowing manual node repositioning. Data is defined in `data.js`, and colors come from a generated palette in `colors.js`.
