A force-directed network chart maps connections among six cities—New York, Los Angeles, Paris, Berlin, Tokyo, and Dubai—using circles for nodes and lines for links. Built with React and D3 v7, the visualization uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position elements, while labels are added as SVG text. The SVG is rendered directly in the browser without an external data file, relying on hardcoded node and link arrays.
