Why does PlantUML C4 diagrams not render correctly on Draw.IO Confluence plug in?

Bhavik Shah_j9lvms

When I use PlantUML in Draw.IO on Confluence plugin, it does not render C4 diagrams correctly with text - there is incorrect spacing and thus the text is hard to read.

 

When I use PlantUML on VScode plugin, this issue does not occur and the text renders fine which suggests that Draw.IO plug in needs updating to the latest PlantUML code.

 

Here is the library I am using:

 

@startuml

!include https/raw.githubusercontent.com/plantuml-stdlib/C4-PlantUML/master/C4_Container.puml

We run a much slower cadence of updating than other PlantUML apps. Each update required a heavy security review that takes around 2-3 weeks. Thus, we do it infrequently.

We also do not add every feature that PlantUML adds, we take a zero tolerance approach to security risks from it.

If PlantUML is very important to you it's strongly recommended to add a PlantUML specific app like https://marketplace.atlassian.com/apps/1215115/plantuml-diagrams-for-confluence?hosting=cloud&tab=overview.
