Abstract :
The formal treatment of visual languages is often based on graph representations. Since the matter of discourse is visual languages, it would be convenient if the formal manipulations could be performed in a visual way. We introduce visual graphs to support this goal. In a visual graph, some nodes are shown as geometric figures, and some edges are represented by geometric relationships between these figures. We investigate mappings between visual and abstract graphs and show their application in semantics definitions for visual languages and in formal manipulations of visual programs
