Id'd via Twitter a May 2015 podcast 'The Fallen of WW2' (18 mins), which extends till then and reminds us we are in a 'Long Peace':
An animated data-driven documentary about war and peace, The Fallen of World War II looks at the human cost of the second World War and sizes up the numbers to other wars in history, including trends in recent conflicts.

It is available in several other languages and there are additional resources on the website:http://www.fallen.io/ww2/

A longer explanation:
The Fallen of World War II is an interactive documentary that examines the human cost of the second World War and the decline in battle deaths in the years since the war. The 15-minute data visualization uses cinematic storytelling techniques to provide viewers with a fresh and dramatic perspective of a pivotal moment in history. The film follows a linear narration, but it allows viewers to pause during key moments to interact with the charts and dig deeper into the numbers.
