*** *Extended deadline: Tutorial and Workshop proposal for Diagrams 2026**** 15th International Conference on the Theory and Application of Diagrams August 24–28, 2026 Tallinn University of Technology, Tallinn, Estonia https://diagrams-conference.org/2026/ *** Highlights *** - Proceedings published by Springer - Graduate Symposium - Three Tracks: Main <https://diagrams-conference.org/2026/calls/main-track/>, Philosophy <https://diagrams-conference.org/2026/calls/philosophy-of-diagrams/>, and Psychology and Education <https://diagrams-conference.org/2026/calls/psychology-and-education/> - Best Paper and Best Student Paper awards ***************************************************************** The Diagrams conference provides a united forum for all researchers with an interest in the study of diagrams. The conference fosters multi-disciplinarity and allows researchers from areas such as computer science, mathematics, psychology, philosophy, history (of science, art, etc.), education research and more to meet and share their perspectives on the theory and application of diagrams. *We invite tutorials consisting of shorter presentations and activities that run for a maximum of 2 hours.* Tutorials are expected to address topics that are of interest to the Diagrams 2026 conference attendees. These include, but are not limited to, the issues of interest found on the Calls pages for the main tracks, philosophy track and psychology & education track. Examples of previous Tutorials include: • Visualizing “Information” • Learning to use the Openbox: A Framework for the Implementation of Heterogeneous Reasoning • Drawing Euler Diagrams for Information Visualization • Representational Systems Theory: What, Why and How? • Square of Opposition: Theory and Applications • Diagrams in the Age of Kant • Euclid’s Elements: The Board Game • Forgotten diagrams and their applications in gestures • Neural Circuit Diagrams: A Diagrammatic Introduction to Deep Learning Models • Cognitive Modelling of Interpretations of Diagrams and Notations *Submission date: April 15, 2026.* More details and important dates can be found at https://diagrams-conference.org/2026/calls-2/tutorials-2/ <https://diagrams-conference.org/2026/calls-2/tutorials-2/> ***************************************************************** *We also invite proposals for half-day or full-day workshops. * *These workshops will be held on the first (August 24, 2026) and the last (August 28, 2026) conference day.* They will occur at the main conference venue at Tallinn University of Technology in Estonia. Workshops are expected to address topics of interest to the Diagrams 2026 conference attendees. These include, but are not limited to, the issues of interest found on the Call pages for the main tracks, philosophy track and psychology & education track. Examples of previous Workshops include: - International Workshop on Set Visualisation and Reasoning - The International Workshop on Euler Diagrams - Technology-Enhanced Diagrams Research - Accessible Graphics: Graphics for Vision-Impaired People - Diagrams and Mathematical Practice - Peirce’s Philosophy of Notation - The Diagrammatic Turn in Quantum Physics *Submission date for workshop proposals: April 15, 2026.* More details and important dates can be found at https://diagrams-conference.org/2026/calls-2/workshops-2/ -- Publicity Chair, Diagrams Conference 2024 Reetu Bhattacharjee, PhD Department of Philosophy University of Münster
