This visualization displays a force-directed network with 13 nodes and 17 links, where node color encodes group membership and link thickness encodes the connection’s value. Using D3 v5, it loads the data via `d3.json`, then applies `d3.forceSimulation` with `d3.forceLink` and `d3.forceManyBody` to position the nodes, while rendering circles and lines as SVG elements that update on each simulation tick.
