A social network graph displays eight people as green circular nodes connected by nine directed links, with thicker lines indicating stronger friendship values. The network layout is computed using d3.forceSimulation with link distance, charge, collision, and centering forces on an SVG canvas. Nodes are draggable via d3.drag, and hovering highlights a node with a green stroke class toggled by mouseover and mouseout events. The data, loaded from a JSON file, specifies relationships and node groups, rendered with D3 v6 selections and a color scale.
