WFP: Country Donors and Recipients [wfp.org] by Santiago Ortiz shows all World Food Programme (WFP) funding from 2003 to present as flows among individual countries.

Each country on the low-polygon count, interactive 3D globe can be selected, in order to reveal how much aid money is directed from and to that specific country. A separate stacked flow chart can be further explored to investigate how popular destinations and origins trend over time.

Reminds me of Google Visualizes Global Transfers of Small Arms and Ammunition.
