A network graph shows social connections among ten individuals, with nodes representing people and lines indicating friend relationships. The graph uses a force-directed layout powered by d3.forceSimulation, with collision detection and charge forces to position the nodes. Nodes are rendered as circles with labels, and links include arrow markers. The visualization is built with D3 v6 and renders to SVG, reading data from a JSON file. Users can drag nodes to reposition them, and hovering over a node triggers a CSS class change for visual feedback.
