This interactive network graph visualizes social connections among nine individuals, with nodes representing people and links showing relationships weighted by thickness. Users can drag nodes to reposition them, while hovering reveals tooltips displaying each person's name. Built with D3.js v4, the visualization uses `d3.layout.force` for physics-based layout, SVG for rendering, and custom mouse event handlers for the tooltip interactions. Data comes from the embedded graph.json file, which defines node groups and link weights.
