Abstract
This paper presents an overview of the established concepts of David Harel' s higraphs, to increase their visibility. Higraphs are a union of extended graph and extended set theory which allows the understandable definition of complex semantics, having a powerful intuitive cognitive nature.
Viewing 'the big picture' is cited as an example of this understandability. A number of other
applications of higraphs are given. Some novel applications are suggested, including the use of higraphs in analyzing business processes, graphical user interface specification, graph domain specification and executable graphs,
A proposition is made that process graphs and data-entity state-transition higraphs are duals. Finally, a case is made for 'informal' higraphs in group communications.
