This visualization displays a network of friends and their connections, with named nodes grouped into clusters and linked by weighted edges. The graph uses D3 v4’s force layout (`d3.layout.force`) to position nodes, while links are drawn as SVG lines whose stroke width reflects link weight. Node circles and labels are rendered via SVG, with hover effects changing their fill and stroke. Data comes from the included `graphFile.json`, and user interaction is enabled through the force drag behavior (`force.drag`), allowing nodes to be repositioned dynamically.
