DRAKON

DRAKON is an algorithmic visual programming and modeling language developed as part of the Soviet Buran space program, following ergonomic design principles. Instead of lines of text it gives a uniform way to represent processes as flowcharts of any complexity, drawn so that they stay easy to read and understand. English Wikipedia dates the start of development to 1986, under the direction of Vladimir Parondzhanov, and says the work was finished in 1996 with a CASE system called Grafit-Floks. The Programming Language Database gives 1996 as its creation year and names Stepan Mitkin, who wrote the DRAKON Editor. That editor was released in September 2011, is available in the public domain, is written in Tcl among other languages, and keeps its source on GitHub. DRAKON is also a family of hybrid languages, such as DRAKON-C and DRAKON-Java, that share one graphical syntax.
