### Abstract

We compare the aﬀordances of two visual logics, one from the Euler family of notations, spider diagrams, and one which takes a signiﬁcantly diﬀerent approach to representing logical concepts, existential graphs. We identify strengths and weaknesses of each notation and present these features as being related to the idea that each notation is, to a greater or lesser degree, biased towards objects or predicates, and that such biases make a notation more or less eﬀective in a given context. We then introduce a framework for understanding and predicting those aﬀordances, which can help guide us towards better use of existing graphical notations and the design of more eﬀective new notations. The framework links research in semiotics and linguistics with insights provided by the HCI and diagrams communities.
