viz: a visual language based on functions
Christopher M. Holt · 2002
The foundations for a visual language called viz are outlined. Some conventions are introduced that are intended to allow a straightforward representation of a functional semantics, while being general enough to be extendible to more general semantic models. The concept of environment is considered, and operations on that environment are interpreted as propositions. State transformers are introduced, permitting the definition of assignments and interprocess communication.>
