World War II's death toll gets rendered as a data visualization, with animated bars and shifting graphs standing in for the more than 70 million people killed. Neil Halloran narrates, starting with military deaths on the Western Front before widening the frame to the Eastern Front, where Soviet losses dwarf every other country's, and then to the civilian toll: the Holocaust, the siege of Leningrad, the bombing campaigns that killed noncombatants in numbers the graphs make impossible to ignore. Comparisons to earlier conflicts, including the Napoleonic Wars and World War I, put the scale of the Second World War in context, and a running tally keeps returning to remind the viewer how much of the total is still unaccounted for. The film closes by tracking the drop in war deaths worldwide since 1945, using the same visual language to argue, cautiously, that global conflict has become rarer. The graphics carry the argument more than any single interview or archival clip does, turning abstract casualty figures into something you can watch accumulate in real time.
