An animated flow map of the automotive supply chain. Arcs connect supplier countries to the selected target assembler country. Arc width represents gross output flow (go_flow) — the actual volume of goods flowing through the supply chain between country pairs.
Reading the map
Arcs flow from supplier → to assembler. Thicker arcs mean larger gross output flows. Colors correspond to the supplier country. The target country is shown with a pill border; click any other node to inspect it.
