A social network graph visualizes connections between nine individuals in a group, with nodes representing people and directed arrows showing relationships. The graph uses a force-directed layout via d3.forceSimulation, applying charge, collision, and center forces to position nodes dynamically. Nodes are rendered as SVG circles with labels, and the simulation updates their positions on each tick. Data comes from a JSON file containing node IDs and group assignments, while links define directed edges. The visualization supports interactive dragging of nodes and highlights nodes on hover using CSS class changes. The implementation uses D3 v6 with SVG rendering.
