[[File:Scatter plot.jpg|right|thumb|Four-dimensional data visualization, using [[VisIt]]: in [[three-dimensional]] [[phase space]] a fourth [[scalar variable]] is visualized by use of coloured glyphs.]]
In the context of [[data visualization]], a [[glyph]] is any marker, such as an arrow or similar marking, used to specify part of a [[scientific visualization|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.
{{Quotation |In the context of data visualization, a glyph is the visual representation of a piece of data where the attributes of a graphical entity are dictated by one or more attributes of a data record. |Matthew O. Ward |Multivariate data glyphs: Principles and practice| In: ''Handbook of data visualization'' (2008), p.180. }}
=== 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 <ref>{{Cite journal|last=Maguire|first=E.|last2=Rocca-Serra|first2=P.|last3=Sansone|first3=S.

=== Examples ===
==== Simple Glyphs ====
'''Complex Glyphs'''
Duffy et al created perhaps one of the most complex glyph representations with their representation of sperm movement.
