This example shows an organization network graph, displaying relationships between arts and social impact organizations in the San Francisco Bay Area. It renders circles and connecting lines as SVG elements, with node sizes varying by hierarchy level. The layout uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to position nodes. Data is defined in a separate module, specifying node sizes and link distances for main, child, and leaf nodes. Text labels identify organizations, and the simulation updates positions on each tick event.
