Tufte would be Proud
The Australian Bureau of Statistics has released a very cool SVG-based animated population pyramid ( non-SVG preview) that very nicely visualises the change in that country’s population over time. While the pyramid technique is fairly common, the addition of a fourth dimension — time — and the ability to track a cohort through it really brings the data to life. Try the “highlight surplus of males or females” feature to see when you’ve got the least competition.
