Clickable Overlays in Visio Online App Part
It is not currently possible to have clickable image overlays in the Visio Online app part. This was functionality supported in legacy Visio Services and we desperately need it back!

To clarify: the use case for having this is so that users can quickly and easily navigate to other related web pages or related items by clicking on an indicator appearing on the shape.
Presently the workaround is to create a side panel which has the information in it, however this approach results in an undesirably and cumbersome UX.
