This is a force-directed network graph built with D3 v6, visualizing trade relationships between countries in 2014. It shows nodes representing countries, colored by group, and links weighted by trade volume, with arrowheads indicating flow direction. The visualization uses `d3.forceSimulation` with link, charge, collision, and center forces, and renders as an SVG. Data comes from a JSON file containing country nodes and weighted links. The graph is interactive, allowing users to drag and reposition nodes within the network layout.
