This example visualizes a force-directed network graph, showing the connections between nodes as a dynamic, web-like structure. The simulation uses `d3.forceSimulation` with link, charge, and center forces to position the nodes, while `d3.drag` enables interactive node movement. The nodes and links are rendered as SVG elements, with node colors derived from a categorical scale based on cluster membership. The code relies on the D3.js library and appears to parse data from a CSV file using `d3.csv` to define the network’s edges and nodes.
