Programming in Graphics. Tomasz Pietrzykowski, Technical U, Halifax. A visual dataflow language. Operation icons are connected by datalinks through which information flows. Supports object orientation. First implemented in Pascal, Acadia U, 1982, later in Prolog at Tech U. Current versions are in C and Prograph.

programs are constructed by directly manipulating a graphical representation of the program. The diagrams are the code; there is no translation to a textual language. PROGRAPH is a fully visual, dataflow-driven programming language designed for RAD (Rapid Application Development). Users have commented on increases in productivity from 3-5 times over traditional text-based languages such as JAVA, C, and C++  It enables the creation of applications through the linking of icons into diagrams, which replaces traditional complex blocks of textual code. This improves software quality by reducing syntax errors. It increases productivity by eliminating lengthy and tedious compile-link-debug cycles. The result is a web development environment, which has resulted in a highly productive , low cost, development environment.
