I attended a one-day course by Edward Tufte in San Francisco today where he discussed his ideas about information display. It was very thought-provoking and he is an excellent speaker. As an added bonus, all attendees got to take home his 3 books, which I plan on digging into soon, they look really interesting. If you ever get the chance to attend his courses, I would highly recommend them. All I can really say is that he's changed the way I look at statistical data and data presentation in general. Definitely worth the time and effort it took to attend. Has anyone else been to a Tufte course? His PowerPoint discussion was just brilliant.
