A social network graph visualizes friendship connections among eight people, with directed arrows showing relationships and yellow circular nodes representing each person. The layout uses a D3 force-directed simulation (`d3.forceSimulation`) with link, charge, collision, and centering forces to position nodes. Interactive drag behavior lets users move nodes, while hovering highlights them via CSS class changes. The graph is rendered as SVG with data loaded from a JSON file, using D3 v6.
