This force-directed network graph visualizes a small social network of five individuals, with weighted links indicating connection strength. The graph uses D3.js v4 with the legacy `d3.layout.force` API, where nodes are draggable circles and lines represent edges with stroke-width proportional to link weight. Data loads from a local `graph.json` file, and the SVG rendering updates positions on each simulation tick, displaying node names as text labels. The visualization applies custom styling to nodes, links, and text within the SVG canvas.
