I saw a link to this on Flowing Data just now. Jessica Hagy is the illustrator and author and she’s been doing similar wonderful work for over 3 years and won countless awards for it.
I think it is a great reminder to those of us working in BI/DW that sometimes we can overwhelm our audiences with information and that there is a trick to finding the right balance.

The temptation is to give lots and lots and lots of information and let the audience worry about interpreting and acting on it. I think I’m guilty of that at times. We’re working on our Exec Dashboard delivery right now and guidance from visualisation experts like Stephen Few points to the same thing - keeping it simple can actually be quite difficult but makes the consumption so much easier.
