How do I create a UML activity diagram in Lucid with PlantUML code?

Hi ​@ichatzieustratiou , welcome to the Lucid Community!

Lucidchart doesn’t currently support PlantUML, but you can still create UML diagrams using our built-in shape libraries and markup tools. If you’re looking for a code-based approach, Lucidchart supports Mermaid code, which might be a good alternative.

You can find more details on Mermaid support here: Diagram as code with Mermaid in Lucidchart.

Let us know how it works for you or if you need any guidance!

Please support PlantUML rendering. You can initially just integrate their binaries into your diagrams and show the rendered diagram. That would be a very handy tool to be able to have a PlantUML diagram on a LucidChart doc tab. Supporting conversion of PlantUML syntax into Lucid Objects can be something for the future.

Hi ​@Timothy.Potter8@T-Mobile.com, thank you for continuing this post. Unfortunately, this isn’t currently supported in Lucid, but we’re very interested in your feedback and committed to continually improving our products. If you’re willing to share, we’d love to hear more details about your use case or what you’d like to see in this experience within this thread. I’ve also converted this post to an idea so that it’s visible to others within the Product Feedback section of the community - from here, they can upvote it and add details of their own.

Until there is a solution from LucidChart, I create the diagram in drawio and then import the diagram as a photo into LucidChart.

Thanks for the update.

The ask is that I would like to keep all of my diagrams in LucidChart (from a diagram repository perspective). I’m already handling the access control in LucidChart, so it is a hassle to have to put my PlantUML rendered diagrams into another repository and have diagrams in 2 different places and handle access control in 2 places. Tons of applications have PlantUML plugins (that handle PlantUML rendering). If I could have a diagram tab that has PlantUML syntax and where a LucidChart has a PlantUML plugin that can convert that syntax into a rendered diagram (can be presented as an image), then I can have all of my diagrams in one place (in LucidChart).
The reality is that PlantUML is awesome for creating things like sequence charts and I (and many others) will use the best tool for the job. For an Architecture Context Diagram, LucidChart is awesome. For creating a sequence diagram, PlantUML is the best tool, in my opinion. So, I want the best of these worlds available in my favorite overall tool - LucidChart. Leianne, let me know if you have questions.
