The Visio Visual does not work with November 2019 release.
Cannot open the visual in PBI desktop.
Had to rollback to October 2019 version to use this visual in my report.
Based on my test in Power BI desktop version 2.75.5649.861, it's able to use Visio visual to display data fine. Please try to update your Power BI desktop to the same version as ours then test again.
