Prograph is a visual programming language that allows developers to draw program flow instead of writing code. It was created by Tom Freeman and Pete Aitken at the University of Calgary in the mid-1980s. In Prograph, the user designs programs using boxes and arrows to represent data transformation processes and control structures. The flowchart-style diagrams automatically generate corresponding code, allowing programmers to abstractly design solutions without getting deep into textual syntax details. Prograph's concept is still influential today, prompting current languages like Scratch or LabVIEW to adopt similar graphical approaches for easier use by beginners or non-programmers in specific domains such as education or scientific research.
