This force-directed node-link diagram visualizes a dolphin social network, showing relationships between individual dolphins as nodes connected by links. The graph uses D3's `forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` functions to position nodes based on network structure. Nodes appear as blue circles with hover tooltips displaying dolphin IDs, and users can drag nodes through D3's drag interaction. The data is loaded as CSV text from a GitHub gist, parsed into nodes and links, and rendered as SVG elements updated on each simulation tick.
