A social network graph displays eight people as orange circles connected by black links, with each person's name labeled beside their node. The network layout is computed using the D3 v4 force simulation (`d3.layout.force`) with gravity, charge, and distance parameters that position nodes dynamically. Data comes from a JSON file (`graph.json`) containing node names and group assignments, plus weighted links between individuals. Users can click and drag any node to rearrange the graph, with link thickness varying according to the weight value of each connection.
