This visualization uses a force-directed layout to display a social network of 11 named individuals, grouped into five clusters by the thickness of their connecting links. The graph is rendered as an SVG using the D3.js v4 and v2 libraries, with the d3.layout.force API managing node attraction, repulsion, and gravity. Node position updates occur on each simulation tick, while circles and text labels are drawn using the SVG `circle` and `text` elements, styled with custom CSS and loaded from the `graph.json` data source.
