This network visualization displays a small social graph with six named nodes and five weighted links connecting them. The visualization uses a force-directed layout to position nodes, with link thickness scaled to the square root of each link's weight. The code relies on d3.v4.js and the older d3.layout.force API to calculate node positions and handle dragging. Links are rendered as orange SVG lines, while nodes appear as blue circles with purple labels taken from the data.json file.
