Prograph is a visual, object-oriented, dataflow, multiparadigm programming language that uses iconic symbols to represent actions to be taken on data. Commercial Prograph software development environments such as Prograph Classic and Prograph CPX were available for the Apple Macintosh and Windows platforms for many years but were eventually withdrawn from the market in the late 1990s. Support for the Prograph language on Mac OS X has recently reappeared with the release of the Marten software development environment.
History
Research on Prograph started at Acadia University in 1982 as a general investigation into dataflow languages, stimulated by a seminar on Functional Languages conducted by Michael Levin. Diagrams were used to clarify the discussion, leading to the insight: "since the diagrams are clearer than the code, why not make the diagrams themselves executable!" Thus Prograph - Programming in Graphics - was born as a visual dataflow language. This work was led by Dr. Tomasz Pietrzykowski, with Stan Matwin and Thomas Muldner co-authoring early papers. From 1983 to 1985, research prototypes were built on a Three Rivers PERQ graphics workstation (in Pascal, with the data visualized as fireballs moving down datalinks), and a VAX with a Tektronix terminal, and an experimental compiler was programmed in an IBM PC. This work was continued at Technical University of Nova Scotia by Pietrzykowski and Dr. Philip Cox, including a version done in Prolog.

電子回路や論理回路（HDL)と考え方が同じなんですよね。配線というか。データフロープログラミング。 RT @beagleboard: Pdのようなビジュアルプログラミング言語って昔Mac用であったPrograph以来さわったんですが、PCよりマイコンの方が相性が良さそうですね。
