This visualization displays a network of connections between organizations funded by the Kenneth Rainin Foundation, with nodes representing main entities, child nodes, and unlabeled leaf nodes. The graph uses d3.forceSimulation with forceManyBody and forceLink to position nodes dynamically, while links are colored to match their source nodes. Node colors are generated from a palette in colors.js, and the SVG rendering updates positions on each simulation tick. Users can drag circles to interact with the graph, and clicking a node triggers the addition of a new main node.
