Well-matchedness in Euler Diagrams
نویسندگان
چکیده
Euler diagrams are used for visualizing set-based information. Closed curves represent sets and the relationship between the curves correspond to relationships between sets. A notation is well-matched to meaning when its syntactic relationships are reflected in the semantic relationships being represented. Euler diagrams are said to be wellmatched to meaning because, for example, curve containment corresponds to the subset relationship. In this paper we explore the concept of well-matchedness in Euler diagrams, considering different levels of well-matchedness. We also discuss how the properties, sometimes called well-formedness conditions, of an Euler diagram relate to the levels of well-matchedness.

Does the Orientation of an Euler Diagram Affect User Comprehension?
Euler diagrams, which form the basis of numerous visual languages, can be an effective representation of information when they are both well-matched and well-formed. However, being well-matched and well-formed alone does not imply effectiveness. Other diagrammatical properties need to be considered. Information visualization theorists have known for some time that orientation has the potential ...
متن کاملExploring the Notion of 'Clutter' in Euler Diagrams
Euler diagrams are an effective and intuitive way of representing relationships between sets. As the number of sets represented grows, Euler diagrams can become ‘cluttered’ and lose some of their intuitive appeal. In this paper we consider various measures of ‘clutter’ for abstract Euler diagrams and show that they compare well with results obtained from an empirical study. We also show that al...
متن کاملOn the drawability of 3D Venn and Euler diagrams
3D Euler diagrams visually represent the set-theoretic notions of intersection, containment and disjointness by using closed, orientable surfaces. In previous work, we introduced 3D Venn and Euler diagrams and formally defined them. In this paper, we consider the drawability of data sets using 3D Venn and Euler diagrams. The specific contributions are as follows. First, we demonstrate that ther...

متن کاملHow can Euler diagrams improve syllogistic reasoning?
The present study investigates the question of whether and how Euler diagrams can improve syllogistic reasoning. Previous research reports that there is no evidence to show the psychological advantage of Euler diagrams in solving syllogisms. In our experiments, we use Euler diagrams with “named points”, which are formulated within the simple Euler system introduced in our previous work. The dia...
