A small co-authorship network shows six fictional authors as nodes and seven collaboration links as edges. Bob, highlighted in red and enlarged, is visually emphasized as the central figure, with thicker links connecting to his co-authors. The example demonstrates a force-directed layout using d3.forceSimulation, d3.forceLink, and d3.forceManyBody for physics-based positioning, while d3.drag enables interactive node manipulation. Node positions update continuously via the simulation's 'tick' event, and SVG circles and lines render the graph.
