This social network graph visualizes relationships among nine individuals, with nodes sized and colored by their connection count and curved links showing ties. The visualization uses D3 v5’s `d3.forceSimulation` for layout, with forces for centering, charge, and link distance. Node drag and drop via `d3.drag` repositions elements, while labels display names. Links are rendered as SVG paths with varying stroke styles, and node fill uses `d3.interpolateBlues` based on weight.
