This social network graph visualizes 19 nodes connected by 14 links, with each node colored by its assigned group using D3's `d3.scaleOrdinal` and `d3.schemeCategory10`. The nodes and links are rendered as SVG circles and lines, with node labels displayed via text elements. The layout is computed dynamically using `d3.forceSimulation`, combining `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to position the network. As the simulation runs, each tick updates the coordinates of the circles, lines, and labels within the SVG container.
