a couple of interactive data visualization that illustrate the structure & content of the past US presidential debates. a "Debate Timeline" depicts the discussion by whom is talking (i.e. question, moderator, McCain or Obama) & the subject, while a treemap shows the main keywords & who mentioned them most. all information is also linked to a textual transcript & video excerpts.
