Labels render on the outside

Hey,
I work for RunKeeper (http://runkeeper.com/home) and we recently decided to add interactive graphs to our mobile apps on iOS and Android. One of my coworkers pointed me in the direction of dc. Our designers wanted the labels to render outside the graphs so I added that functionality. I thought it'd be cool to share it with the community as a thanks for an awesome library! The graphs will be live in our app in about a week if you want to check them out. Thanks!
