A force-directed graph visualizes a social network of eight people connected to a central "University" node, with all links labeled as "Friend with." The D3 v6 visualization uses `d3.forceSimulation` with link, charge, collision, and center forces to position nodes, which are rendered as yellow circles with name labels. The graph is drawn as an SVG, with links as lines and node markers, and nodes support drag-and-drop interactions. Hovering a node highlights it with a green outline, while the viewBox attribute ensures the visualization remains responsive.
