I'm Kim. I'm generally a sarcastic asshole. Some people appreciate it. Others, not so much.
I believe infographics and charts have a rectangle-square relationship. Charts (squares) are always infographics (rectangles) because they are graphics which contain information. Infographics, however, may contain other things that extend beyond the limits of charts.
Basically, http://ilovecharts.tumblr.com/ is my favorite blog ever.
