A social network graph displays ten people connected by “Friend with” relationships, with node size and link thickness varying by connection value. The visualization uses d3.forceSimulation with forceLink, forceManyBody, forceCollide, and forceCenter to position nodes, while drag interaction lets viewers rearrange the layout. Nodes render as SVG circles with labels, and links are drawn as lines with arrow markers, all colored by a simple green palette. Data loads from a local graph.json file containing the node and edge definitions.
