All--

You might find these videos by Hans Rosling on presenting health data extremely useful/interesting.  The first is a 4 minute long YouTube video (I know some of you cannot watch YouTube from your work computers).  The second is 18 minutes long, but is available on a blog.  If you have an opportunity to view these, you will agree that these are exceptional presentations.

Thanks to Alan Pisarski for sharing this with us.
