Organization Graph Diagram
This example shows an organization graph diagram constructed from a custom dataset in `data.js`, where main nodes branch into child nodes and smaller anonymous leaves. The visualization uses D3 v7 with `forceSimulation`, `forceManyBody`, `forceLink`, and `forceCenter` to position nodes as gray circles of varying sizes, connected by black lines, with text labels. The simulation runs continuously, updating the SVG circles, lines, and text positions on each tick, rendering the hierarchical network layout.
