A sunburst is a design or figure commonly used in architectural ornaments and design patterns and possibly pattern books. It consists of rays or "beams" radiating out from a central disk in the manner of sunbeams.[1] Sometimes part of a sunburst, a semicircular or semi-elliptical shape, is used. Traditional sunburst motifs usually show the rays narrowing as they get further from the centre; from the later 19th century they often get wider, as in the Japanese Rising Sun Flag, which is more appropriate in optical terms.
Sunbursts can appear in photographs when taking a picture of the Sun through the diaphragm of a lens set to a narrow aperture due to diffraction; the effect is often called a sunstar.[2]
In information visualization, a sunburst diagram or sunburst chart is a multilevel pie chart used to represent the proportion of different values found at each level in a hierarchy.
