Wow.  Gathering together data from the Death Penalty Information Center as well as pre-1976 data from M. Watt Espy and John Ortiz Smykla, Time Magazine (hat tip to Chris Wilson, Emily Maltby and Lon Tweeten) has put together a really amazing compilation regarding the death penalty in America.

Go here to read, " Every Execution in U.S. History in a Single Chart."

You’ll learn a lot. 

Like there have been executions in this country by burning people to death

And the most popular form of execution in the USA?  Hanging. 

Worth your time to peruse and ponder.
