This network graph visualizes a small social network of seven friends, showing connections between individuals with varying link weights. The graph uses a force-directed layout to position nodes, with red circles representing each person and labels displaying their names. The visualization is built using D3.js v4, employing the legacy `d3.layout.force` API for node positioning and drag interactions. Data comes from a JSON file containing node names, group assignments, and weighted links, rendered as SVG lines with stroke-width proportional to connection weight. The graph automatically positions nodes based on the force simulation, with links drawn between connected friends.
