A visual dataflow programming language and environment from the Technical
University of Halifax.
Prograph is an entirely graphical visual programming language, other than for
the text of method names, and supports the program development process in a
highly-interactive fashion. Operation icons are connected by data links through
which information flows. It supports object orientation via class-based data
abstraction with single inheritance.
Prograph is available for the Macintosh, and soon for Windows and Unix, from TGS
