Last week many American observed 11 September in remembrance of the terror attacks that brought down the Twin Towers, a section of the Pentagon, and four airliners in total. So this week we are going to see some fantastic work from Periscopic that highlights several other terror groups operating in the world across the last few decades.
The charts work as a timeline from 1970 through 2013 and then vertically from January through December. Above and below the timeline, respectively, are the numbers of people killed and wounded. When shown as small multiples, the overall piece can show you which groups have been active and lethal, active but without lots of fatal attacks, and those that are fading out or fading in.
Credit for the piece goes to Periscopic.
