This social network graph visualizes friendships among eight people using a force-directed layout with red circular nodes and labeled text. It uses `d3.forceSimulation` with link, charge, collision, and center forces to position nodes and edges. The D3 v6 code loads data from `data.json`, renders the graph as SVG with arrowhead markers on links, and supports drag interaction. Hovering highlights a node by turning its border green.
