Periscopic, a Portland, Oregon-based data visualizing firm designed an eye-catching a dynamic visualization to depict the remaining years for each person might have lived if their lives hadn’t been cut short by a bullet. They used FBI gun murders data in 2010 and 2013 and U.S. mortality data from the World Health Organization for the visualization. 
Golden or red arcs across a black screen and fades to gray, it showed ages of victims died when the arcs turn to grey and showed the ages of these victims might have lived when the arcs touch the horizontal line. Also, you can see the count of stolen years for these victims at the right corner.
When exploring the source code generating the graph, you will find javascript codes were used to create this amazing visualization. If you are interested in the graph, you can visit http://guns.periscopic.com/?year=2013
