As visual languages become more popular, it becomes more important to have a formal framework for reasoning about their syntax, semantics, and the relationship between them. This paper is concerned with outlining a possible approach. It begins by looking at textual languages from a geometric point of view, and goes on to suggest how this may be generalized so as to be useful in understanding visual (especially dataflow-style) languages.
