The Raven - Visualized

Inspired by Martin Wattenberg's The Shape of Song , I decided to create a similar visualization but using text as input rather than music. I used Edgar Allen Poe's The Raven for my first attempt. Each arc is a connection between one occurrence of a word and the next occurrence of that same word. The color of an arc is determined by the distance between the two occurrences, with colors ranging from green to red.
