Just found this intersting graphical animation of the new 2006 statistics of the development of our world!
Gapminder is a Stockholm-based non-profit organisation. Their extraordinary interactive graphs help to visualize complex global trends, like the distribution of poverty, in different regions of the world. All animation have also a timeline included and show very well how and where changes occur. The raw statistics would bore you to tears; the web graphs — dynamic, colorful and clear — are utterly compelling.
Another example is the world health chart.
