This example shows a small interactive force-directed network of six nodes labeled A through F, connected by six weighted links. The data from a JSON file includes attributes such as gender and profession, though the visualization primarily focuses on node connections and link thickness proportional to edge value. Users can drag nodes to reposition the network. The code uses d3.forceSimulation with centering, charge, and link forces, rendering nodes as SVG circles with text labels and titles via d3.
