Program Visualization

The Icon variant described here — MT Icon — fell into disrepair and was ultimately removed from the Icon source code; so this page is mainly of historical interest.

Program visualization, sometimes called software visualization, is the visual representation of progam activity during execution. It attempts to make use of the immense capability of the human visual system to make such activity comprehensible.

Icon has been used extensively as both a target for program visualization and as a tool for building program visualization software.
