A Universal Grammar for Specifying Visualization Types

Abstract A ‘universal grammar’ for the full spectrum of visualization types is discussed. The grammar enables analysis any type regarding its syntactic constituents, such as visual encodings and components that are used. Such an a visualization, describing compositional syntax, can be represented specification tree. Colour coded tree branches between constituent enforce combination rules visually. We discuss how these trees differ from linguistic parse trees, statements verbal statements. offers basis generating options, potential formalization machine-readable specifications. This may serve system providing computer-generated advice.
