This has been an interesting topic for me for a long time. In the earliest ventures to popularize the ways to visualize data or information, Edward Tufte, Yale University statistion, wrote a book called, "The Visual Display of Quantitative Information," (1983) and then "Envisioning Information" (1990). We'll this stirred many an imagination and now we have sites, such as www.informationisbeautiful.net. This site does a wonderful job at showing how we can find & learn the complex answer to a question with a single, clever graphic. Try this page, that answers the question: "How much caffeine do I have each day?" It displays the various kinds of drink by caffeine and sugar levels. Wonderful.
