This network visualization displays nodes and links loaded from two CSV files, with link width encoding edge weight. The code uses `d3.forceSimulation` with `forceLink`, `forceManyBody`, and `forceCenter` to position nodes, while `d3.scaleOrdinal` colors nodes by team affiliation. Nodes are rendered as SVG `<circle>` elements with draggable behavior via D3’s drag API, and a tooltip appears on mouseover showing node ID and team. Labels sit beside each node, and the simulation updates positions on each tick.
