This visualization displays a social network with nine people as nodes and eight weighted connections as links, rendered as an SVG using D3.js. It shows relationships between individuals, where line thickness corresponds to link weight. The graph uses the D3 v4 `d3.layout.force` API for physics-based layout with gravity, charge, and distance parameters, allowing nodes to be click-dragged. Node positions update during the force simulation’s tick events, while labels and styled circles mark each person. Data comes from an embedded graph.json file containing names, group assignments, and connection weights.
