Functional Unification Approach to Automated Visualization Design

Stephan Kerpedjiev, Steven F. Roth, and Joe Mattis

A unification-based approach to visualization design provides a uniform way of representing user requirements, design knowledge, and graphic designs as well as algorithms for synthesizing graphic presentations. We demonstrate this approach on two types of requirements -- structural in the form of sketches and functional in the form of tasks. With this approach we aim to achieve the following system design goals: expressiveness (the formalism can express the visualization design problem and its problem-solving algorithms), uniformity (the same formalism can be applied to different generation tasks), efficiency (graphics can be designed in a reasonable amount of time), and extensibility (the system can be extended with new types of requirements, design elements and design knowledge).
