I once saw an After Action Report that used an aerial shot of Fallujah superimposed with colored dots to show various contact with the enemy (e.g. red for IEDs, green for snipers, etc.). Does anyone know if a similar thing exists for Baghdad that covers the recent sectarian violence?

Basically, I'm curious where the violence is happening. Is it throughout the city? Or is it confined to specific areas such as Sadr city? The media makes it sound like the entire city is in flames.
