 Our usual way of communicating is with words. Written words consist of single symbols (letters), gaining meaning when arranged in certain combinations. The question is, if there are basic visual symbols that, arranged in a particular way, can be used to convey information in a similar manner.

 Since nowadays information is presented by computers, the addition of '''motion''' as a new visual variable becomes important.  Changes in motion can include direction, speed, frequency, rhythm, flicker, trails, and style. [Carpendale, 2003]

 Choosing different visual variables for representing different aspects of the same information can greatly influence the perception and understanding of the presented information. It is therefore important to know and appropriately use the characteristics of visual variables when creating ''any'' visual data representation.
