This social network graph visualizes friendship connections between people, with each node labeled by name and linked by directed edges using arrow markers. The graph uses a force-directed layout via `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to position nodes and reveal clustering. Nodes are interactive circles with hover effects and dragging support, rendered as SVG using D3 v6’s `select` and `selectAll` APIs. The data is loaded from a JSON file containing nodes and links with relationship metadata.
