A force-directed graph shows the network of organizations connected to the Kenneth Rainin Foundation, with four main nodes branching into smaller child nodes and leaf nodes. The visualization uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position elements, rendered as SVG circles and lines with labels. Dragging nodes via the `drag` interaction updates their fixed positions. Node colors are sourced from a palette in `colors.js`, and link distances vary by hierarchy level.
