Glyphs are basically composite graphical objects where different geometric and visual attributes are used to encode multidimensional data structures in combination.
A primitive example of a glyph is an arrow whose visual attributes length, width, angle, and color might be used to encode four different data attributes in a single graphical object.
The most prominent example for glyphs are Chernoff Faces [Chernoff, 1973], where the different parts of a conceptualized human face (mouth, nose, head, eyes, eyebrows, etc.) encode different dimensions of an n-dimensional data set.

Glyphs in Typography
The specific graphical representation (shape) of a character is called a glyph. Glyphs are the minimal units of font information.
A character is a textual unit, whereas a glyph is a graphical unit. Sometimes several characters or only parts of one glyph — consider ligatures as an example.
