In 2008 I made some U.S. movie box office visualizations that were pretty popular. I got a lot of nice comments and links from respected designers and movie lovers. Github even used the style as the basis of their impact graphs.
I've been updating the charts each week since 2008. To coincide with publishing the final 2010 movie chart, I've published the Lisp code for drawing the charts. It's not polished or documented, but in keeping with my new project release policy, I hope someone finds it useful or interesting in some way.
