This network graph visualizes a "best friend circle" with three main nodes (Sameer, Likit, Aravind) connected to intermediary subscriber and network system nodes, ultimately linking all friends in a chain. The SVG rendering uses React with d3-force simulation, specifically `d3.forceSimulation` combining `forceManyBody` with strength -100, `forceLink` with per-link distances, and `forceCenter`. Nodes appear as rounded rectangles colored by type (orange, yellow, teal) with draggable interaction via `d3.drag`. Node sizes distinguish main (150px), child (60px), and leaf nodes in the data-driven layout.
