Visual Language

Program-Transformation.Org: The Program Transformation Wiki

A visual language is a ProgrammingLanguage^? that uses pictures to depict the instructions of a program and their relations.

Visual languages can also be used in ProgramUnderstanding to visualize some aspect of a program.

I would think that an example of a Visual Language is UML or SDL; I associate a control flow diagram more with SoftwareVisualization. -- ArieVanDeursen
