Nightingale Rose Chart (Nightingale's polar area diagram  or occasionally the Nightingale rose diagram), equivalent to a modern circular histogram, to illustrate seasonal sources of patient mortality in the military field hospital Florence Nightingale managed, was published in Notes on Matters Affecting the Health, Efficiency, and Hospital Administration of the British Army and sent to Queen Victoria in 1858. According to the historian Hugh Small, "she may have been the first to use [pie charts] for persuading people of the need for change."
