This network graph visualizes relationships among car brands, with nodes representing Volkswagen, Audi, Skoda, Porsche, Bentley, and Bugatti, and links indicating connections weighted by strength. The code uses d3.layout.force (from d3.v2/v4) to simulate a force-directed layout, rendering SVG circles and text labels for nodes and pink lines for links. Link thickness scales with the square root of the weight from graphFile.json, and nodes are draggable via force.drag. The graph updates positions on each tick event, translating node groups and adjusting link endpoints.
