Swizec Teller, author of Data Visualization with d3.js, is a geek with a hat. He founded his first start-up at the age of 21 years and is now looking for the next big idea as a full-stack Web generalist focusing on freelancing for early-stage start-up companies. When he isn't coding, he's usually blogging, writing books, or giving talks at various non-conference events in Slovenia and nearby countries. He is still looking for a chance to speak at a big international conference. In November 2012, he started writing Why Programmers Work At Night, and set out on a quest to improve the lives of developers everywhere.
I want to thank @gandalfar and @robertbasic for egging me on while writing and being my guinea pigs for the examples. I also want to send love to everyone at @psywerx for keeping me sane and creating one of the best datasets ever.
