   Among Nightingale’s innovations: the Polar-Area Diagrams that she used to represent the impact of poor sanitation and transmissible diseases on the mortality rate of British soldiers during the Crimean War.

   This diagram was part of her "Notes on Matters Affecting the Health, Efficiency, and Hospital Administration of the British Army" submitted to Queen Victoria in 1858. You can see a copy here: https://archive.org/details/b20387118/page/n7/mode/2up
