This network graph displays eight employees and their weighted connections using a force-directed layout. The visualization reads data from a local `data.json` file and renders nodes as red circles with blue text labels, while purple links vary in stroke width according to each connection’s weight. The graph uses the older `d3.layout.force` API to apply gravity, charge, and distance parameters that position the nodes. SVG is the rendering approach, with drag interactions enabled through the force layout’s drag method.
