Interactive map visualizes Mexico’s drug war

 

Coder and data enthusiast Diego Valle-Jones developed an interactive map that tracks drug war-related homicides in Mexico.

The map allows users to compare total homicides and drug-related homicides over time. Filters can be used to specify the type of drug associated with the homicide: marijuana, opium and cocaine.

Users can click on a bubble on the map to get information about the number and type of homicides in a particular location up to 2004. A timeline feature enables the user to track the evolution of drug war-related homicides in a specific region between 2004 and 2010.

"The really cool thing about the map is that it makes it very easy to select regions of Mexico and link directly to them, which makes refuting mistaken claims by government officials, like the one Poiré made last year, a cinch" he wrote on his blog, also adding that "the map is a work in progress and is still missing the cocaine routes, but hopefully I'll be able to add them shortly."

For homicide data Valle-Jones used as sources Mexico's National Institute of Statistics and Geography (INEGI) and Citizen's Institute for the Study of Insecurity (ICESI). 

In creating this project the developer was inspired by some of the charts on the Learning R blog and the Junkcharts blog

The interactive map can be accessed on Valle-Jones' blog. The source code for this project is available on Github.
