This interactive network graph visualizes a small social network of six people and their connections. Nodes are orange circles with labels, and links are gray lines; hovering turns a node red and displays a tooltip. Users can drag nodes to rearrange the layout. The visualization uses the D3.js library, specifically the `d3.forceSimulation` API with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` for physics-based layout, alongside custom drag functions and SVG rendering.
