Wikipedia is all well and good, but sometimes all that text can be overwhelming. Sometimes you just want to kick back, relax and rely on the sweet educational embrace of a good old fashioned chart.

If this sounds like you, then you need Useful Charts, the most useful chart related – well, you probably get where that's going.

Useful Charts is the passion project of Matt Baker, a psychology PhD candidate from Vancouver, who wants to make the world's knowledge accessible to visual learners. From Aristotle's Four Causes of Existence explained in box form to an index of Muppet voice actors to Erik Erikson's 8 Stages of Human Development conveyed in neat rows and columns, it's a handy reference guide for, well, a lot of things, both frivolous and not. More than anything, it's just nice to be off Wikipedia for a while.
