This social network graph visualizes friendships among eight people, with green circular nodes labeled by name and connected by thick black directed edges with arrowheads. The layout uses a force-directed simulation (`d3.forceSimulation`) with link, charge, collision, and centering forces. Nodes are draggable via D3’s drag behavior, and hovering highlights a node’s border. Data comes from a local `data.json` file containing node IDs and link relationships. The visualization is rendered as SVG using D3 v6, with all nodes sharing a single group color.
