Useful Charts

Useful Charts is a website of, well, useful charts. The charts tend to be table heavy and not so strong on design (but not so bad, either), but there are still a ton of useful, interesting charts here, particularly on history, English, psychology, astronomy (well, some) and pop sci-fi (but hard science, mathematics, economics, and law ... not so much).

The charts creator is Matt Baker, who has a Google+ account with even more charts (many from others), and a blog with even more charts (even more from others).  On the whole a really great source for graphical displays of information.
