One of the areas I have been exploring here on Neoformix is the notion of constructing graphics in an algorithmic fashion from textual data. The site NOTCOT has just published an article on some interesting work by Stephanie Posavec that explores this same idea. She has constructed a number of different works based on the text of Kerouacís On the Road. From NOTCOT's article:
The maps visually represent the rhythm and structure of Kerouacís literary space, creating works that are not only gorgeous from the point of view of graphic design, but also exhibit scientific rigor and precision in their formulation: meticulous scouring the surface of the text, highlighting and noting sentence length, prosody and themes, Posavecís approach to the text is not unlike that of a surveyor.
Here are a few images that will give you a taste and a rough idea of what they mean. Although definitely more on the artistic side of information visualization, I like these images and the ideas behind them a great deal.
