A social network graph displays six people grouped by category—Family, Friends, or Work—with colored nodes and labeled connections. The visualization uses a D3 force-directed layout via `d3.forceSimulation`, `forceLink`, and `forceManyBody` to position nodes and links dynamically. Node colors are mapped with a `d3.scaleOrdinal` against a hardcoded dataset of names and relationships. Interactions are minimal, with the simulation updating SVG circle and line positions on each tick.
