Visio 2013 provides new features designed to help you create diagrams more intuitively--including new and updated shapes and stencils, improved effects and themes, and a coauthoring feature that makes teamwork easier. You can also make your diagrams more dynamic by linking shapes to real-time data and then share them with others through a browser using Visio Services in SharePoint, even if they don't have Visio installed.
