Glyph (data visualization)

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.

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.

Four-dimensional data visualization, using VisIt: in three-dimensional phase space a fourth scalar variable is visualized by use of coloured glyphs.

Information Visualization (InfoVis)

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.[1]

Examples

Simple Glyphs

Complex Glyphs

Duffy et al created perhaps one of the most complex glyph representations with their representation of sperm movement.

Scientific Visualization (SciVis)

Key Advantages

It helps visualizing data relation in Data Analysis, Statistics, etc. by using any custom notation.
