For some reason I’ll never understand, I have always been enthralled by flow charts. To me they are always fun to look at, in part because it’s such an interesting visual way to learn more about yourself. Recently NPR celebrated the top 100 science fiction and fantasy books of all time. You can go to their intricate flow chart and see, based on your own preferences, which of the 100 most awesome of scifi fantasy books most closely matches your personality: http://www.sfsignal.com/archives/2011/09/flowchart_for_navigating_nprs_top_100_sff_books/
On a side note, I will definitely have to do a future post on other cool visual data in book publishing. There’s a very interesting visual showing the gender discrepancy between published books and professional book reviews – but that’s a story for another day (and another post!).
