abstract = {Annotations are central to effective data communication, yet most
visualization tools treat them as secondary constructs – manually defined, difficult to
reuse, and loosely coupled to the underlying visualization grammar. We propose a
declarative extension to Wilkinson’s Grammar of Graphics that reifies annotations as
first-class design elements, enabling structured specification of annotation targets,
types, and positioning strategies. To demonstrate the utility of our approach, we
develop a prototype extension called Vega-Lite Annotation. Through comparison with eight
existing tools, we show that our approach enhances expressiveness, reduces authoring
effort, and enables portable, semantically integrated annotation workflows.}
