Visio is a program for Microsoft Windows that allows the user to create visual diagrams, vector graphics and charts. Stencils for Visio are collections of shapes and images that can be appended to documents created in the program. As of 2015, Visio also allows users to link sections of a diagram to other documents that contain additional information. This feature is compatible with Microsoft Excel, Business Connectivity Services, SQL Server and SharePoint Lists.
