A week ago, I posted an animated map of coup attempts worldwide since 1946 (here). Unfortunately, those maps were built from a country-year data set, so we couldn’t see multiple attempts within a single country over the course of a year. As it happens, though, the lists of coup attempts on which that animation was based does specify the dates of those events. So why toss out all that information?
To get a sharper picture of the distribution of coup attempts across space and time, I rebuilt my mashed-up list of coup attempts from the original sources (Powell & Thyne and Marshall), but now with the dates included. Where only a month was given, I pegged the event to the first day of that month. To avoid double-counting, I then deleted events that appeared to be duplicates (same outcome in the same country within a single week). Finally, to get the animation in CartoDB to give a proper sense of elapsed time, I embedded the results in a larger data frame of all dates over the 68-year period observed. You can find the daily data on my Google Drive (here).
WordPress won’t seem to let me embed the results of my mapping directly in this post, but you can see and interact with the results at CartoDB (here). I think this version shows more clearly how much the rate of coup attempts has slowed in the past couple of decades, and it still does a good job of showing change over time in the geographic distribution of these events.
The two things I can’t figure out how to do so far are 1) to use color to differentiate between successful and failed attempts and 2) to show the year or month and year in the visualization so we know where we are in time. For differentiating by outcome, there’s a variable in the data set that does this, but it looks like the current implementation of the Torque option in CartoDB won’t let me show multiple layers or differentiate between the events by type. On showing the date, I have no clue. If anyone knows how to do either of these things, please let me know.
