This interactive network graph visualizes a social network of friends, with nodes representing individuals and links showing their connections. The layout is computed using D3's force-directed simulation, combining `d3.forceSimulation` with `forceLink`, `forceManyBody`, `forceCollide`, and `forceCenter` to position nodes with repulsion and attraction. Rendered as an SVG, the graph reads JSON data from a GitHub gist and displays each node as a circle with a label, using colored lines and styling from CSS.
