This example shows a small force-directed network of six tech companies and research organizations, with weighted links representing collaborations. It uses D3 v7’s `d3.forceSimulation` with a link force, many-body charge force, and centering force to position nodes. Nodes are rendered as colored SVG circles based on type (company, research, hardware), with draggable behavior via `d3.drag`. Links appear as gray lines, and labels display each entity’s name. The simulation updates node and link positions on each tick.
