A network visualization displays three named nodes—Alice, Bob, and Carol—connected by directed links, rendered as circles and lines in an SVG. Using d3.forceSimulation with forceManyBody, forceLink, and forceCenter, the layout animates positions on each tick. The example demonstrates importing data via d3.csv and integrating D3 force layouts within a React component, though the visible data is hardcoded while the CSV file remains unused.
