This social network graph visualizes interconnected room nodes, with main nodes colored orange or blue based on their checked status, while child and leaf nodes remain transparent. The example uses a simple tree structure where user `trucntx007` defines connectors between rooms, using the `d3.forceSimulation` API with `d3.forceManyBody`, `d3.forceLink`, and `d3.forceCenter` to simulate physical forces for layout. Rendering in SVG, the graph applies drag interactions and zoom functionality, and clicking a node triggers an alert with a VK profile URL.
