For those of you interested in deeper exploration of how to more effectively display ideas, particularly relating to data, I highly recommend the work of Edward Tufte. Tufte is an award winning author and emeritus professor at Yale where he taught courses on data analysis and display. His books and teaching are challenging and force you to move beyond powerpoint and overly simplified forms of information display.
I often teach principles of simplicity in message and communication. Tufte is very effective at pointing out and teaching how to make “simple” powerful without being “simplistic”. There are very data rich and complex ways to show information that are also intuitive and easy to understand. His writings are rich with examples and are beautifully built. The books themselves are works of art.
His site has multiple commentary threads that are worth reading. In addition, I recommend checking out his essay on the tyranny of powerpoint.
