Visualization of the depth of Lake Victoria
**_Bathymetry_** (ba·thym·e·try - /bəˈTHimətrē/) - the measurement of depth of water in oceans, seas, or lakes. The map shown above illustrates the depth of Lake Victoria in East Africa. The GeoJSON powering this visualization was adapted from TIFF files shared on the [Harvard Dataverse](https://dataverse.harvard.edu/dataset.xhtml?persistentId=doi:10.7910/DVN/SOEKNR) ### What is Akuko?
