A social network of 11 named people and 11 weighted connections is visualized as a force-directed graph, with nodes representing individuals and link thickness encoding connection weight. The graph loads from a local `graph.json` file, and the D3 v4 library builds an SVG scene with circles and text labels. Using `d3.layout.force` with gravity, charge, and distance parameters, the simulation positions nodes dynamically, while user interaction enables dragging to rearrange the layout. Styling applies a pink-and-red color palette to links and node strokes.
