This example visualizes a collaboration network among three authors and three papers, using a force-directed simulation to position the six nodes. D3.js v6 APIs such as `d3.forceSimulation`, `d3.forceLink`, and `d3.forceManyBody` compute the layout, while SVG circles and lines render the nodes and edges. Purple and blue colors distinguish author and paper groups, and users can drag nodes to interact with the simulation, which updates positions and labels on each tick.
