An interactive organization graph rendered in SVG with D3's force-directed layout. The visualization shows four main nodes connected by links, with child nodes and small leaf nodes branching from each main node, all colored using a palette from a generated colors module. The code uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position nodes, with node sizes and link distances defined in the data. As the simulation ticks, circles, lines, and text labels update their positions dynamically.
