Visio Online integration with Microsoft Flow.
SharePoint workflows used to integrate with Visio, allowing developers to create a Visio Diagram that was easily understood and easily implemented as a workflow. It would be cool if you could build out a Microsoft Flow in Visio.
Thanks for the suggestion. This is under consideration.
