A force-directed network graph displays seven named nodes connected by weighted links, with node size and stroke thickness reflecting link weights. The visualization uses the D3 v4 force layout (d3.forceSimulation) to position and drag nodes interactively, rendering SVG circles, yellow text labels, and green link lines on a pink background. Data originates from a local JSON file containing node groups and link weights. Custom styles define red circle borders, aqua fills, and cursor behavior, while the force simulation applies gravity, distance, and charge parameters.
