Language visualisation: Applications and theoretical foundations of a primitive-based approach

Language visualisation consists of using consistent and systematic mappings between language expressions and graphical forms, where the graphical forms constitute or convey the meaning of the expressions. Primitive-based applications are described for both natural and artificial language (story visualisation and program visualisation, respectively). On the basis of these and other applications some foundational concepts are identified in a bottom-up theory of visualisation. A universal visualisation system architecture is proposed, as is a basic visual object taxonomy for classifying any visualisation object. Also, preliminary steps are taken towards constructing a top-down theory.
