Microsoft Visio (viz-zee-oh) is a diagramming and vector graphics application and is part of the Microsoft Office family. Visio can be useful for creating organization structures, network structures, room layouts, relational diagrams, process diagrams, flow charts, and more. Visio can also use UML (Universal Markup Language) to interface with database schemas. Visio starts with a set of templates that allow a user to easily develop a diagram using a preconfigured set of stencils, icons, and markup for a specific purpose. Additional templates and stencils can be downloaded via the Office Download Center. Users can also create from a blank template and use any stencils and objects from any library available.
Visio is not part of the standard Office installation and must be licensed and installed separately. It is only available on the Windows Platform.
