Glyph (data visualization)
{{Short description|Visual representation of a piece of data}}

In the context of data visualization, a glyph is any marker, such as an arrow or similar marking, used to specify part of a visualization. This is a representation to visualize data where the data set is presented as a collection of visual objects. These visual objects are collectively called a glyph. It helps visualizing data relation in data analysis, statistics, etc. by using any custom notation.

Constructing glyphs
Glyph construction can be a complex process when there are many dimensions to be represented in the visualization. Maguire et al proposed a taxonomy based approach to glyph-design that uses a tree to guide the visual encodings used to representation various data items.{{Cite journal |last1=Maguire |first1=E. |last2=Rocca-Serra|first2=P. |last3=Sansone |first3=S.

Duffy et al created perhaps one of the most complex glyph representations with their representation of sperm movement.{{Citation needed|reason=Citation for the original work containing the glyphs as well as a source that makes the claim that it is the most complex glyph representation.|date=February 2019}}
