Euler diagram codes: interpretation and generation

Abstract

Euler diagrams (EDs) are a popular means of visualizing set-based relationships. We describe the advancement of EulerSketch, based on a novel encoding of EDs. In particular, EulerSketch allows a user to sketch and interact with EDs and automatically produce a code representation for them. It also enables code storage and retrieval and permits to automatically re-draw an ED from its code representation. Some features are inspired by earlier works [4, 6, 3].
