{{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.

=== 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.
