This week’s resource up for discussion: The Preservation of Favoured Traces
One of many visualization projects of Ben Fry, this page shows you how the Origin of Species changed over time, allowing for both broad and detailed views of the text. Though perhaps not suitable for rigorous textual analysis, could this be of real value for getting a sense of a large corpus? Is it just eye candy?
Also, you might check out some other (not always historical) examples of visualization at http://processing.org/exhibition. These are examples of using an open-source programming language (called Processing, created by Fry) often used to visualize data. Did you get any ideas about how you represent some of your own ideas and concepts?
