This network visualization shows a bipartite graph of three authors connected to three papers through authorship relations, with authors as circles and papers as squares. The layout is generated using D3's `d3.forceSimulation` with link, many-body charge, center, and collision forces, allowing nodes to be repositioned via mouse drag. The rendering uses D3's `symbol` API for distinct node shapes, SVG paths for nodes, and `d3.select` joins for interactive elements like hover tooltips and a legend. The example demonstrates D3 v7's force-directed graph capabilities in a simple, self-contained dataset.
