A bar chart titled "Deaths from Wars & Cars" the Leftmost bar is WW2 at 78M, followed by Cars 72M, Mongols 39M, Taiping 25M, Ming Qing 25M, 2nd CN-JP 20M, and finally WW1 19M. A note at the bottom states "Showing estimate midpoints"
You have the granularity of individual wars yet the composite of all car/vehicle deaths (worldwide?) compared to each other. The chart just appeals to the abstract and doesn't really offer much use other than to inflame the reader's emotions.
