<p>In the new Visio, we have re-envisioned our Unified Modeling Language (UML) templates in a fresh, modern way. We updated our five most popular UML diagrams, with all new shapes to make it easier and faster to create beautiful, professional diagrams. Our new UML templates allow you to create class, sequence, state machine, activity and use case diagrams that match the UML 2.4 standard. The templates focus on a freeform, on-canvas experience. Each template takes advantage of the full capabilities of Visio, including shape effects and themes, as well as collaboration and commenting to share your diagrams across your organization. In this article we'll introduce each of the new UML diagrams and present a few tips about using the new model.</p>
