Sunburst

A sunburst is a design or figure commonly used in architectural ornaments and design patterns. It consists of rays or "beams" radiating out from a central disk in the manner of sunbeams. 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.

In architecture, the sunburst is often used in window designs, including fanlights and rose windows, as well as in decorative motifs. The sunburst motif is characteristic of Baroque church metalwork, especially monstrances and votive crowns, and Art Deco and Art Nouveau styles as well as church architecture. A sunburst is frequently used in emblems and military decorations.

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.

Dragon

A dragon is a legendary creature, typically with serpentine or reptilian traits, that features in the myths of many cultures. There are two distinct cultural traditions of dragons: the European dragon, derived from European folk traditions and ultimately related to Greek and Middle Eastern mythologies, and the Chinese dragon, with counterparts in Japan (namely the Japanese dragon), Korea and other East Asian countries.

The two traditions may have evolved separately, but have influenced each other to a certain extent, particularly with the cross-cultural contact of recent centuries. The English word dragon derives from Greek δράκων (drákōn), "dragon, serpent of huge size, water-snake".

Name

The word dragon entered the English language in the early 13th century from Old French dragon, which in turn comes from Latin draconem (nominative draco) meaning "huge serpent, dragon", from the Greek word δράκων, drakon (genitive drakontos, δράκοντος) "serpent, giant seafish". The Greek and Latin term referred to any great serpent, not necessarily mythological, and this usage was also current in English up to the 18th century.
