This example visualizes a social network of eight people using a force-directed graph rendered with SVG. The graph shows people as cyan nodes with labels and their friendships as green arrowed lines, with the relationship type and connection strength encoded in the data. The layout is driven by d3.forceSimulation with link, charge, collision, and center forces, and nodes are interactive via d3.drag, highlighting on hover. The code loads node and link data from a JSON file and uses D3 v6 within a React application.
