A fork of the D3 network graph example visualizes a social network of ten people, with circular nodes representing individuals and directed links showing friendship relationships. The graph uses a force-directed layout via `d3.forceSimulation` with forces for link distance, charge repulsion, collision detection, and centering. Nodes are draggable, and hovering highlights them. Data is loaded from a JSON file containing nodes and links with relationship metadata. The visualization is rendered as an SVG with green circles, red labels, and blue arrows, using D3 v6.
