The importance of toplogy in diagrams is discussed, and higraphs are defined.
Abstract: this article is to extend and combine Euler's two topo-visual formalisms into a tool suitable for dealing with such cases. In the next section, we introduce higraphs, 4 first mod- ifying Euler/Venn diagrams somewhat. then extending tlem to represent the Cartesian product. and finally connecting the resulting curves by edges or hyperedges. [The appendix contains the formal syntax and seman- tics of simple higraphs.} We will then illustrate the power of the formalism by briefly discussing... (Update)
