Interactive tool, dubbed The World of Terror, offers users a glimpse into GTD-based terrrorist trends

Periscopic, a data visualization firm that promotes information transparency and public awareness, has produced an innovative, interactive tool that allows users to explore the impact and dynamics of the START Global Terrorism Database (GTD) perpetrator groups. A World of Terror examines the 25 perpetrators that were most active between 1970 and 2013, visualizing their attack patterns across multiple dimensions including life span, recency, casualties, and geographic spread.
