A social network graph of eight people and eleven "Friend with" relationships, with nodes as red circles labeled by name and directed links with arrowheads. The d3.forceSimulation, d3.forceLink, d3.forceManyBody, d3.forceCollide, and d3.forceCenter APIs compute node positions, while SVG circles and lines render the result. Hovering highlights a node with a green stroke. Data comes from a static JSON file containing link endpoints and node IDs.
