Anyone who likes strange charts like this should check out Edward Tufte&#8217;s <a href="http://www.amazon.com/Visual-Display-Quantitative-Information/dp/096139210X">The Visual Display of Quantitative Information</a>. It&#8217;s long been one of my favorite books. Thank you to my friend Tina for color advice, and to my brother Ricky for some Lord of the Rings detail corrections.</p>
<p>Also thank you to Olga and Noam for the lovely <a href="http://www.vimeo.com/7151435">animated version of comic #442</a>.</p>
