German designer Milan Vuckovic (previously at Neatorama) compiled terrorist attacks over the past 15 years, between December of 2000 and November of 2015. This visualization follows a timeline at the bottom showing where attacks took place and roughly the number of people killed. Every death is a tragedy, but for accuracy and simplicity, the attacks plotted were limited to those in which twenty or more people died.
While the 9/11 attacks produced the highest number of casualties, you can’t help but notice that some areas of the world endure these incidents constantly. And they have since long before the beginning of this century. It’s a sad sequence, beautifully presented. -Thanks, Milan!
