A visualization is considered to be expressive if the relevant information of a dataset (and only this) is expressed by the visualization. The term "relevant" implies that expressiveness of a visualization can only be assessed regarding a particular user working with the visual representation to achieve certain goals.
Don Norman calls this "Appropriateness principle" in [Norman, 1993]:
Appropriateness principle: The representation used by the artifact should provide exactly the information acceptable to the task: neither more nor less.
