This is a visualisation of activity in Afghanistan from 2004 to 2009 based on the Wikileaks data set. Here we're thinking of activity as the number of events logged in a small region of the map over a 1 month window. These events consist of all the different types of activity going on in Afghanistan.
The intensity of the heatmap represents the number of events/atttacks logged. The colour range is from 0 to 60+ events over a one month window. We cap the colour range at 60 events so that low intensity activity involving just a handful of events can be seen - in lots of cases there are many more than 60 events in one particular region. The heatmap is constructed for every day in the period from 2004-2009, and the movie runs at 10 days per second.
The orange lines represent the major roads in Afghanistan, and the black outlines are the individual administrative regions.
