Take a look at gun deaths, school shootings, public opinion and the Senate vote on gun control in the wake of the massacre at Sandy Hook Elementary School in Newtown, Conn., that killed 26 people, including 20 children.

As Slate editors note in the introduction to their crowdsourced map that attempts to visualize gun deaths in the US (pictured below), determining the actual number of gun deaths each year is “surprisingly hard.” That’s because as many as 60 percent of gun deaths are suicides that usually go unreported by the press.
