A pre-release, Version 0.92, was distributed free on a floppy disk along with a Microsoft Windows systems readiness evaluation utility. Visio began as a standalone product produced by Shapeware Corporation version 1.0 shipped in 1992. Visio also supports saving files in SVG files, other diagramming files and images. VSDX and VSDM files use the same compression as Zip files. Hence, a VDX file typically takes up 3 to 5 times more storage. While VSD files use LZW-like lossless compression, VDX is not compressed. Since these files are susceptible to macro virus infection, the program enforces strict security on them. VSDX and VSDM files differ only in that VSDM files may contain macros. Created based on Open Packaging Conventions (OPC) standard (ISO 29500, Part 2), a VSDX or VSDM file consists of a group of XML files archived inside a Zip file. Visio 2013 drops support for writing VDX files in favor of the new VSDX and VSDM file formats, and uses them by default. Visio 2010 added support for the VDX file format, which is a well-documented XML Schema-based ('DatadiagramML') format, but still uses VSD by default. vss (right) filesĪll of the previous versions of Visio used VSD, the proprietary binary-file format. ĭatabase modeling in Visio revolves around a Database Model Diagram (DMD). A few new features have been added such as one-step connectivity with Excel data, information rights management (IRM) protection for Visio files, modernized shapes for office layout, detailed shapes for site plans, updated shapes for floor plans, modern shapes for home plans, IEEE compliant shapes for electrical diagrams, new range of starter diagrams, and new themes for the Visio interface. On 22 September 2015, Visio 2016 was released alongside Microsoft Office 2016. Visio Professional is also offered as an additional component of an Office 365 subscription. The Professional edition features three additional diagram types, as well as intelligent rules, validation, and subprocess (diagram breakdown).

The Standard and Professional editions share the same interface, but the Professional edition has additional templates for more advanced diagrams and layouts, as well as capabilities intended to make it easy for users to connect their diagrams to data sources and to display their data graphically. Microsoft made Visio 2013 for Windows available in two editions: Standard and Professional.
