On the readability of diagrammatic proofs

Recently, much effort has been placed on developing diagrammatic logics, with a focus on obtaining sound and complete reasoning systems. A hypothesis of the diagrammatic reasoning community is that many people find diagrammatic proofs easier to read than symbolic proofs. This hypothesis has not been thoroughly tested, although significant effort has been directed towards understanding what makes diagrams more readable than symbolic formulae. We are interested in how to automatically find readable diagrammatic proofs. To achieve this aim, significant research is required that builds on the existing state-of-the-art. This extended abstract summarizes our plans for research on this topic.
