Reams of data, mountains of evidence… it’s just difficult to convey it. Especially these days because 1. people are rather impatient and want their information right now, 2. we have so much data, we just can’t sift through it all. So what better than a picture to make it all clear.
Take a look at these pictures. They make things quite clear.
(thanx, Linoge… you’ve always got good stuff)

Thanks for the link!
It is incumbent, as always, on the person presenting the information to make that data as approachable and understandable as possible… The good news is that the graphics are surprisingly simple, given the topics in question… and now they are a lot easier to find, too!
Thanx for the link? Well, thank YOU for making such awesome graphics and making them freely available to anyone willing to take a few minutes to look and want to understand facts and data.
alas, not everyone cares for such things….
