A social network diagram shows ten fictional people grouped by academic department, with colored nodes and gray edges representing connections. Red links highlight relationships between members of different groups, such as Math and English. The visualization uses D3 v5’s `forceSimulation` with `forceLink` and `forceManyBody` to position nodes, while SVG circles and text labels render each person’s name. A `scaleOrdinal` with `schemeCategory10` assigns distinct colors to each department, and a tick handler updates node and link coordinates.
