This interactive force-directed graph visualizes a city transportation network, showing direct connections between eight U.S. cities as labeled nodes and links. Built with D3 v7 and rendered as SVG, it uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to position the nodes. Drag behavior, implemented via d3.drag, allows users to reposition nodes. A legend identifies the single "City Node" category, and all elements update dynamically on each simulation tick.
