The International Workshop on Set Visualization and Reasoning (previously called the Euler Diagrams Workshop) aims to bring together researchers in the field. The community publishes in a diverse range of outlets, hence a single workshop provides a unique opportunity to share ideas and practice. The topics of the workshop includes established set representations like Euler/Venn diagrams and matrices as well as new formalisms, such as linear diagrams and linesets. The workshop scope covers methods for laying out, reasoning with and evaluating set visualizations.
