World statistical data on TED like you have never seen it presented before by Dr. Hans Rosling. Take 20 minutes to watch this video. Very impressive data presented in an innovative and thought provoking way. (Watch for the drama around the 4:00 mark)
The site and data studies that Dr. Rosling refers to can be found at : http://gapminder.org/ The X and Y criteria can be changed making for hours of interesting and dynamic graphing.
Click the 'play' button on this one for example to chart the relationship between 'Life Expectancy' and 'Income Per Person' and watch Canada's growth over the past 100 years. A word of warning. This site can become quite addictive.
