This interactive force-directed graph visualizes the network of connections between nodes, with circle size representing node importance and link thickness indicating connection weight. Built with React and D3 v6, the visualization uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position nodes dynamically. The SVG rendering displays node labels and link labels that rotate along the edge angle. Users can drag nodes to reposition them, triggering simulation restarts. The data originates from a CSV file and includes a button to add new main nodes to the diagram.
