This interactive network graph visualizes connections among a group of friends, with nodes representing individuals and links showing relationships. The D3.js force-directed layout uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to position nodes, while d3-force provides drag interaction. Node colors come from d3.schemeCategory10 based on group membership (1 or 2). The SVG rendering includes node labels and link thickness scaled by connection value. Users can drag nodes to explore the network, with zoom functionality via d3.zoom.
