This force-directed network diagram shows relationships between authors and papers, with orange circles representing authors and blue circles representing papers. Links connect authors to their papers and include a direct connection between Alice and Charlie. The visualization uses `d3.forceSimulation` with link, charge, and center forces to compute the layout, and supports interactive dragging of nodes. Node size and color differentiate the two node types, while labels display each entity’s name. The code draws SVG lines for links and grouped circles with text for nodes, updating positions on each simulation tick.
