The ability to annotate a visualization, for example a chart or graph, would make both the dashboard and reports experience more robust.
I would like to be able to use the same Annotate and Share features available in the mobile app, in the online app. The same as seen here https://docs.microsoft.com/en-us/power-bi/consumer/mobile/mobile-annotate-and-share-a-tile-from-the-mobile-apps
