Gapminder
( www.gapminder.org ) at the UN development Program.

This is just the coolest thing i've ever seen.

It's fun and has a good point. But most notably, it is simply the best presentation of data i have ever seen. Most graphs and charts make the data unclear, impenetrable; sometimes it is on purpose, but mostly it's just out of ignorance.

This not only shows clearly what the data is and what it means, but it is presented in a way to be intuitively interpreted. It's just easy to understand the data. I wish all data were presented this well.

They make use of what The Master, Edward Tufte might call, chartjunk, however it is used in a way that enhances and explains beautifully. Rather than cluttering and confusing like usual.

The UN development Program has several other statistical presentations available, although this is the best.
