Refresh shape feature should be available
We can refresh data but looks like there is no way we can refresh an updated visio diagram in Power BI. We need to reload the visio diagram and due course the data mapping is lost. Now we need to re-bind the data. It would be great if we have a feature of reloading the updated diagram and just map the data for newly added blocks.
Refresh the diagram by expanding the field mapping window and clicking on Refresh diagram button.
