This network visualizes bilateral merchandise trade among the 100 economies included in the 2025 dataset. Each circle represents an economy, sized by its total trade with the other economies in the dataset and colored by region. Connections represent bilateral trading relationships, with thicker lines indicating greater trade volume. To keep the dense global network readable, the visualization emphasizes the largest trade relationships. **Source:** International Monetary Fund (IMF), *International Trade in Goods (by partner country) (IMTS)*, formerly *Direction of Trade Statistics (DOTS)*, 2025 data; visualization based on the 2025 top-100-economy extract. IMF describes IMTS as its dataset of merchandise exports and imports disaggregated by trading partner.
