This example shows a hierarchical organization graph with a single parent node connected to two child nodes, one of which branches into six identically labeled "anonymous" nodes. The graph is rendered as SVG circles and text labels connected by black lines. The code builds the node and link data manually using exported arrays and a custom helper function. It uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to compute the layout, with node positions updated on each simulation tick.
