This project by Moritz Stefaner shows the development of global trade flows in the last decade. It was developed for citibank to investigate and demonstrate insights about mid-term economic trends.
The application shows the development of imports and exports in 40 selected countries over the last decade. Users can play back the last ten years on a world map or an ordered display of the countries similar to beads on a string, sorted by trade volume, balance, or latitude.
