This interactive network graph visualizes social connections among nine individuals, with undirected links representing friendship and each node labeled with a person's name. The graph uses a physics-based layout via D3's `forceSimulation`, incorporating link, many-body charge, collision, and center forces to position nodes. Users can drag nodes to rearrange the network, with hover highlighting indicating the selected node. The data comes from a JSON file, rendered as SVG circles and lines.
