A village of 100 people
I'm a big fan of graphics that try to convert macrostatistics in something more affordable.
And a good example of that is the web A Village of 100 people, which takes world statistics and shrink them to the hypothesis that the whole world is a little village of 100 people. How many gays would be? And how many children will go to school? How many people would die per year?
The web has very good things and some not-so-good (some data is told but not drawn, there's no a general example on how the village would be with the 100 people,, some examples play with percentages instead of keeping the metaphor...), but anyway it keeps being a great way of funny pedagogy
