The LA Times has put together a visualization summarizing the Mexican drug war.  You'll notice that they have included information on key players, number of deaths (by week and location), and indicated regional hotspots.  There are also some great interactive components within this graphic.  You can adjust the timeline, associate each key player with a location, and filter by topic or location.  If you were to use this visualization as a tool to summarize the drug war in Mexico, what other information would you want to see?
