Health and Wealth - Visualizing Data

Hans Rosling is a master of using data and graphics to show the health and wealth of the world.  By animating the data he shows how things have changed over time.  I really like his approach to make it very clear what is happening.  There is a definite trend towards health and wealth in the world...  That's a reassuring thing.  I also think its really interesting to see the effect of wars and disease on populations and how it makes their bubbles bounce around.  Take a look for yourself.
