I came across this interesting project via twitter. While the exact approach does not carry over to history (the project visualized a social network using the dialogue in 19th century British novels, but, unfortunately, most of the “dialogue” of history gets lost), it makes the project I am working on for my digital history seminar (visualizing social and political networks) seem more timely. I just wish they put the project online (or if they have done so, provided a link).
