This bar chart shows the number of armed conflicts in the world from 1946 to 2013. Data is from the [Uppsala Data Conflict Program (UDCP)] (http://www.pcr.uu.se/research/ucdp/datasets/). The largest number of conflicts was in 1991: 52 conflicts.

The bar chart expands upon the [Let's Make a Bar Chart tutorials] (http://bost.ocks.org/mike/bar/).

And just for information's sake, here is a list of the locations of the 52 unique conflicts occuring in 1991, the peak year for the data.
