US Gun Deaths in Contrast

Since the Sandy Hook shooting tragedy, the gun issue in the US is being seriously (and sometimes irrationally) debated while the families and community struggle with their loss and grief.  Being from a country with gun regulations, it is hard to watch and read some of the extreme misinformation being spouted.

I don't think there's a country on the planet that doesn't have some gun deaths each year, but there are plenty who have put in place measures aimed to reduce the volumes. The countries below represent nations similar to US culture, many of whom have enacted some form of regulation as a result of a similar tragedy.

This viz is particularly small as I'm curious to see how it interacts on a smart phone.  Let me know if you have any suggestions.  Too much information for a small space?  Does the interactivity make sense?
