A friend did this for a school project! It was super cool - Harry potter was cool because the later books took on different shapes, which to me showed one of the reasons such a simple set of stories got so popular (Book 1 is Cinderella; Book 5 is Kafka; Book 7 is "Man in a Hole", etc.). But ultimately, on real data, what it boiled down to is "there are only so many general shapes you can plot in 2D." It apparently became a very manual visualization process: the normalization problems (book length, length of good/bad bits, etc.) from different texts swamped any new shapes one could conceivably identify using the method.
