Save money, and replace Visio, Lucidchart, Lucidspark, and Miro with a SmartDraw site license.
The free SmartDraw Connectors for Confluence and Jira let you connect to your existing SmartDraw account and access and embed any diagrams you created in SmartDraw.
You can use the same diagram on multiple pages and issues and when the original is updated, all copies will be updated automatically.
