A social network graph visualizes friend connections among eight people, with nodes labeled by name and directed, arrow-tipped links indicating relationships. The force-directed layout uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, `d3.forceCollide`, and `d3.forceCenter` to position nodes. Nodes are draggable via `d3.drag`, and hovering highlights a node with a green stroke. The SVG output is rendered with D3 v6, using data from a JSON file.
