Microsoft Visio is diagramming software for flowcharts, mind maps, org charts, network diagrams, floor plans and timelines, with templates and shape libraries. It runs as a web app and, with Visio Plan 2, as a desktop app with offline use and data linking to sources such as Excel, SQL Server and SharePoint. Visio integrates with Teams, Power BI, Office applications, OneDrive and Azure and is delivered through Microsoft 365 subscriptions. Standard and Professional are also available as one-time desktop purchases.
Microsoft Corporation is headquartered in the United States, so Visio falls under US jurisdiction, including the CLOUD Act. The Visio Online licensing terms refer to Microsoft's Data Protection Addendum. Visio does not appear on Microsoft's list of Microsoft 365 services with data-residency commitments; where files are stored follows the Microsoft 365 tenant model. European organisations can check the data location of their tenant and consider alternative diagramming tools.
