This interactive force-directed graph visualizes a small social network of nine people connected by eight weighted links, with node labels showing names and link thickness encoding connection weight. The visualization uses D3.js v4 with the legacy `d3.layout.force` API, rendering nodes as red circles with yellow strokes and black connecting lines in an SVG container. Users can click and drag individual nodes to rearrange the network, while the simulation updates positions during tick events to maintain the layout. The data comes from a local `graph.json` file with node and link arrays.
