The International Workshop on Set Visualization and Reasoning has grown from the workshop series on Euler Diagrams, which first ran in 2004. Since then, the Euler Diagrams Workshop successfully ran in 2005, 2012, 2014 and 2016. The renaming of the workshop series reflects a broadening of research in this area to encompass a wider variety of techniques for visualizing and reasoning about sets. Whilst Euler diagrams, and the closely related family of Venn diagrams, continue to be widely studied, new notations have been devised. Techniques include KelpFusion, which uses Euler-like diagrams to represent sets, and Linear diagrams, which use line segments to represent sets.

Euler diagrams have become the foundations of various visual languages and have notably facilitated the modelling of, and logical reasoning about, complex systems. As new notations come on-line, this workshop series provides a focal point for both early-stage research alongside more advanced contributions, enabling a better understanding of how we visualize and reason about sets. Application areas for this research are broad and encompass many other disciplines, sich as biosciences, business, and criminology.
