This visualization displays a small social network of nine named individuals organized into five groups, with weighted connections represented by lines whose thickness scales with link weight. Using D3.js v4 and a force-directed layout, nodes are rendered as blue circles with red name labels and are draggable. The code employs `d3.layout.force` for simulation, with gravity, charge, and distance parameters, and loads node and link data from an external `graph.json` file. The SVG output includes dynamic positioning updated on each tick event.
