State Diagram Examples in Lucidchart

Lucidchart regularly publishes free example templates for UML diagrams, including state diagrams. State diagrams, also known as state machine diagrams, show how objects transition from one state to another. The templates below capture these transitions on a basic level for an airport check-in system, a calendar system, and an online shopping system. You can edit any Lucidchart document with our ultra-intuitive software, modifying fonts, colors, sizes, and shapes. It's also simple to include additional shapes or even combine multiple diagrams. Once you've explored these examples, try making your own diagram from scratch. Feel free to check out this handy guide on drawing state diagrams for more information.
