Provided is a process, including: obtaining a set of candidate captions associated with one or more data visualizations; obtaining criteria designating whether candidate captions are descriptive of potential instances of the one or more data visualizations; producing a plurality of simulated instances of each of the one or more data visualizations; determining which of the captions apply to each of the simulated instances of each of the one or more data visualizations based on whether the simulated instances satisfy corresponding criteria; causing captions determined to be applicable to be presented; receiving feedback indicative of whether presented captions are perceived as descriptive of the corresponding simulated instances of data visualizations; and adjusting the criteria based on the feedback.
