The ability to annotate a visualization, for example a chart or graph, would make both the dashboard and reports experience more robust.
David has described the need well, and I agree the Tableau annotation features are a good model. The "Enlighten Data Story" custom visual (in PowerBI marketplace) provides some of the features (combining static text and measures), but the need is to have something like this embedded in other visuals and linked to data points with relative positioning. Would you recommend starting a new thread, since the original poster didn't provide any detail?
