Nightingale Charts

Nightingale charts (also called Rose or Coxcomb charts) are a circular variant of bar charts where each segment occupies the same angle but extends outward to a radius proportional to its value. Popularized by Florence Nightingale for medical data, they are effective for cyclical data where the circular layout reinforces periodicity.
