A force-directed network graph maps seven hobby-related nodes, including Laptops, VR, Games, and Audience, with weighted links that vary in thickness. The graph uses d3.json to load the graphFile.json data, and a custom force layout (d3.layout.force) with gravity, distance, and charge settings to position nodes. Nodes are draggable SVG circles with text labels, rendered with yellow fill and red stroke, while links are purple lines with width proportional to the square root of each connection's weight.
