A fork of the Social_Network_graph_ICE-8 example visualizes a small social network of nine named individuals across five groups, with weighted links between them. It uses `d3.layout.force` in D3 v4 to position the nodes as circles connected by black lines, where line thickness reflects link weight. The graph loads its data from a local `graph.json` file, renders to SVG, and supports interactive dragging of nodes via `force.drag`. Node labels appear in red text beside each blue circle, with styling defined by CSS classes.
