A visual discourse is a series of connected visual displays. A coherent visual discourse is characterized by smooth transitions between displays, consistent design within and across displays, and successful integration of new information into existing displays. We use a top-down, hierarchical decomposition, partial order planner to efficiently construct a visual discourse from scratch, taking advantage of parametrized primitive visual objects that serve as building blocks in the design process. Visual representations are modeled as visual objects, graphical techniques are employed as planning operators, and design policies are encoded as constraints. This approach not only improves computational efficiency compared to search-based approaches, but also facilitates knowledge encoding, and ensures global coherency.
