Edward Tufte

He's the king of the infographic. As I said before, I love infographics. Here are some things that he invented:

1) Small multiples: they're a series of small similar pictures that are repetitive and make their point through their repetitiveness 

2) Sparklines:  it's a simple condensed way to measure some trends and variation, like temperature, stock prices, and rain levels.

He's done a lot more. I want to read more about him. 

Anyway, that is all.
