Population dispersion infographic

This infographic shows the municipalities population distribution in relation to the distance from the capitals of Brazilian states (preliminary data from Census 2010)*.

Move the mouse over the points /stantes/regions to explore them. You can also click and drag the outer circle to calculate how many live in a range of (i.g.) 300 km from the capitals.

Thanks Prof. Romulo Krafta for the tip.

*It's a peculiar way to visualize urban hierarchy as well.
