What is the Nightingale’s Rose chart?
In this graph, the proportional areas are plotted in a polar coordinate system, divided into equal segments (with the same angle). Differences between categories and groups are made visually evident through the filled areas of these segments.
The invention of this diagram is attributed to Florence Nightingale—a British nurse and social reformer, who in 1858 developed this chart type to represent the causes of death of British soldiers during the Crimean War graphically. Her rose chart is especially appropriate (but not only) to visualize seasonal/periodic data. Check the examples to get inspired!
Curiosity: Meteorologists use this graph as a tool to visualize the distribution of wind speed and direction on a location. This meteorological chart is called “wind rose” and uses the compass rose as a reference to display the principal winds (cardinal and ordinal directions).
