Re: Feedback Request: Custom Visuals V1 APIs Suggestions

 When init or update is called, it would be helpful to have a unique ID for the visual (and additionally an ID for any data object in the dataView, like categories and values). For our product this would be used in server-side API hits while debugging.

Separately, it would be cool to have a read-only API for seeing what other objects (and therefore selected data) are on the page. Use case: our extension could list existing objects on the page and have the user select which one to use as a data source, instead of them configuring our visual with the same dimensions/measures.
