Neil Halloran, creator of the excellent Fallen of World War II interactive visualization of the casualties of WWII, is working on a similar visualization about the possible effects of a global nuclear conflict. He recently uploaded an in-progress video of the project with a special 2016 election message at the end. Amazing and scary to see how much of a difference WWII made in the global death rate and how minuscule that would be in comparison to a global nuclear war.
