A force-directed organization graph displays a personal network centered on John Doe, with main connections to Google and Facebook and their related sub-nodes like YouTube, Amazon, and Messenger. The visualization uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter to position nodes, while SVG circles and lines render the hierarchy. Node sizes vary by depth, and colors are generated from a predefined palette in colors.js. Users can drag nodes, which fixes their position and restarts the simulation.
