This is an animated version of the following pie map ...

Pie charts aren't highly though of by data visualization purists,
because of their several drawbacks.  But a lot of users who aren't
educated in the evils of pie charts "like" them, so I thought I'd
try to include a few examples that aren't all that bad a use of them :)

If you're going to use a pie chart, it's probably best to use them in 
situations where you're trying to show the contribution of a part
to the whole, and where you have a very small number of slices 
(ideally, the minimal 2 slices, as in this example).  The human 
eye is very good at determining whether one slice is bigger than
the other, therefore it's easy to tell whether male, or female,
clothing sales is higher.

This particular example shows clothing sales in department stores,
and the pie slices show the % male & female sales (by the pie slices),
as well as compare the total department store sales between the 
states by the size (area) of the pies.

I think this animated version provides more insight than the 
static version (that only shows 1 year) - but I still recommend
looking at the data in other ways, to see specific trends and
comparisons.
