This image shows firearms statistics at a scale of 1 pixel = 1 person. [CORRECTION: The scale is 1 pixel = 4 people. Anyway, the areas of the circles are proportional.] By necessity, the pixel dimensions are gigantic. However, it's a compressed PNG so the file size is quite small (270 KB).

"Events like this," I said, "if they are influenced by anything, are influenced by news programs like your own. When an unbalanced kid walks into a school and starts shooting, it becomes a major media event. Cable news drops ordinary programming and goes around the clock with it. The story is assigned a logo and a theme song; these two kids were packaged as the Trench Coat Mafia. The message is clear to other disturbed kids around the country: If I shoot up my school, I can be famous. The TV will talk about nothing else but me. Experts will try to figure out what I was thinking. The kids and teachers at school will see they shouldn't have messed with me. I'll go out in a blaze of glory."
