Tree-map the world, part 1

I got a hankering for tree-maps, so I decided to visualize some nominally hierarchical data about our world. Click through on the header links to see the interactive tree-maps. The static images here are best viewed on wide devices. Data is mostly sourced from Wikipedia, so don’t take this as authoritative.

Choose your adventure:
Language | Population | GDP | Govt. Budget | Religion | Species

*Only the charts at: https://jsfiddle.net/user/TreeMapTheWorld/fiddles/ are originals! Others may be derived copies we have no control or responsibility over.

This is the first in a series of articles on visualizations. See Part 2.
