This doesn't have anything to do with Analytic Journalism per se, but while flying from Cairo to Dubai recently I looked out the window at 39,000 feet somewhere over the sands of central Saudi Arabia.  What to my wondering eyes did appear, but an expanse of pie charts. 



Of course these are irrigated crops.  A friend in Dubai, who grew up in Saudi Arabia, said the reason they are not all completely filled circles is because some growers don't have enough money (yet) to buy the equipment necessary to complete the 360-degree irrigation.
