School Shootings in the US



This map displays the casualties and fatalities in school shootings in the US from 1997-2012. It is based on data drawn from the Brady Center to Prevent Gun Violence.

This is not a great chart — the size of the circles creates a perceptual problem (each school shooting doesnt cover a 200 square mile area) and the coloring of the legend is not at all intuitive (wait is purple good or bad?) — but even with that, the sheer volume of School Shootings surprised me.
