Tutorials: From Decisions to Designs: A Hands-On Tutorial with the Typology of Decision-Making Tasks
Organizers: Camelia Daniela Brumar, Remco Chang
Designing visualizations for decision-making often requires structuring complex, multi-stage workflows that remain implicit during the design process. This hands-on tutorial introduces the Typology of Decision-Making Tasks for Visualization, a concise framework for modeling decision workflows using three composable tasks: choose, activate, and create. Participants will learn how to represent decision problems as structured node-link diagrams that make task hierarchy, information flow, and iteration explicit. Through guided small-group exercises, attendees will model a real-world decision-support scenario and then translate their task diagrams into visualization design sketches. The tutorial emphasizes the transition from structured problem definition to interface design, demonstrating how different decision tasks naturally inform interaction components, layout structure, and system logic. Designed for visualization researchers, designers, and practitioners at all experience levels, the tutorial combines conceptual foundations with collaborative exercises and discussion. Participants will leave with a practical methodology for externalizing decision problems and using them as blueprints for designing interactive decision-support visualizations.
