Whiskers II: whole lot of shavin' going on

The pie charts I did the other day - about the facial hair of US presidents and British PMs - got me thinking: what is the current political state of facial hair in the world?

So I did some research. And it wasn't as easy as I had first thought. Some countries are simple to check, cos they have someone who's clearly completely in charge, at the top of the tree (Kim Jong-il, Gordon Brown, Luis Inácio Lula da Silva, etc.); but there are plenty of nations that have presidents and prime ministers, and it's sometimes difficult to work out who has the power, and whether the president is mainly just a ceremonial position. I've done my best. If I made any mistakes, please let me know.

I kinda obsessed on it a bit... working on it from about 8pm 'til 3am last night. And doing the pie charts wasn't enough, oh no: it seemed like a good idea to also express this information as a map, which you can see below the pie charts. (Note: North America includes the Caribbean nations.)

So, what have we learned? Well, firstly, that there aren't many women in charge; that African leaders like a 'tache; as do those in southern Asia and the (horribly-named) Middle East; and I learned that my assumption that South America would have lots of moustaches was utterly wrong.

Update: Conor mentioned in the comments that Robert Mugabe has a moustache. He's right. I didn't even notice it; I just thought it was a shadow rather than a wispy, slightly-Hitlerian moustache. The map and pie charts have been amended accordingly.
