Summary0018410: Graphviz version 2.40.x does not generate correct graphs when used with PlantUML
DescriptionPlantUML is a widely used tool for generating documentation. The version of graphviz that is shipped with CentOS Stream is 2.40.x which produces incorrect graphs with PlantUML. The attached images show the difference between the graphviz 2.40.x version (default in CentOS Stream) and the 2.50.x version which I compiled directly from the upstream repository (

When diagnosing this problem, I found many folks using CentOS/RedHat that could not properly produce diagrams whereas it worked fine on Ubuntu and other variants.
Steps To ReproduceDownload the plantuml jar from (
Create a test UML diagram (see attachment for example code).
Generate a test image: java -jar plantuml.jar example.pu

Additional InformationPer, GraphViz versions 2.39 - 2.42 do not work well.

The 2.50 build appears to be relatively straightforward. Except for some Java dependencies (looking for java-devel versus java-latest-openjsk-devel or similar), the build was mostly painless.
TagsNo tags attached.
