A network graph visualization displays a "My Friends Network Graph," mapping relationships between individuals as labeled nodes connected by lines. The visualization uses d3.forceSimulation with forceLink, forceManyBody, forceCollide, and forceCenter to position nodes, preventing overlap and maintaining layout stability. Nodes are rendered as light blue circles with navy text labels, while links appear as thick black lines. Data is loaded from a remote JSON file, and the SVG output is scaled through a viewBox attribute for responsive display.
