A method for modeling and graphically comparing incidence rates of adverse events that vary over geographical regions is shown and discussed. To achieve our goal, we used a statistical model to compare incidence rates and showed how informative three-dimensional graphs of such incidence rates can be created dynamically using R and interactively controlled using Google Earth with Keyhole Markup Language (KML). These methods are applied to the terrorism events in regions of Southern Thailand that occurred from 2004 to 2009.
