This network visualization shows a small social graph of seven named individuals with weighted connections between them, rendered as green nodes with yellow labels on a black background. The force-directed layout, built with d3.layout.force from d3.v4, positions nodes and links while supporting drag interaction. The code loads data from data.json via d3.json, then uses SVG line elements for links with stroke-width determined by the square root of each link's weight, and groups for nodes with attached circles and text labels.
