I'm starting to hear about Charles Minard's map of Napoleon's march time and time again - almost to the point of exhaustion. Is the map really that awesome, or is it just because Edward Tufte said so? Here is my question to all of you:
Is Minard's map the best statistical graphic ever drawn?
I have my own thoughts about this, but more importantly, I want to know what you all think. If you don't think it's the best ever, what is? If you do think it's the greatest of all time, what's second best?
