This interactive D3.js network visualization maps a hypothetical research collaboration graph, showing seven researchers and their seven co-authorship ties. Nodes are color-coded and shaped by academic role—circles for professors, squares for postdocs, triangles for students—using d3.symbol with distinct symbol types. The layout relies on d3.forceSimulation with forceLink, forceManyBody, and forceCenter to position nodes, while drag interactions let users rearrange the graph. The force-directed simulation updates node coordinates on each tick, rendering an SVG with animated link movements and static labels.
