Yesterday, we created a graphic -- based on a Congressional Research Service study -- showing the cost of every major U.S. war. Today we decided to do another graphic, this one on U.S. military deaths in each war. There's a snapshot on your left. You can also look at the full graphic -- along with the option to view the number of deaths as a ratio to the U.S. population at the time. (We created the graphic using a free Web site from IBM called ManyEyes.)
