Hello,

This may be related with the version of GraphViz your are using.

Could you check it with :

@startuml
testdot
@enduml

Your example seems indeed to work fine on the online server:

installing last version (-2.39.20160519.1619) does not fix the problem

Maybe should I downgrade to 2.38.0 ?
commented May 20, 2016 by plantuml (230,800 points)
Yes, I think that this bug occurs with 2.39. So try to downgrade to 2.38
commented May 21, 2016 by junkw (240 points)
Yup, 2.38 fixed this.
Thanks for help, appreciated

Bug seems to be fixed, graphviz 2.40.1 doesn't have that problem anymore.

A similar problem still occurs with Mac OS X, graphviz 2.40.1 and 2.41_devel.  When using containers and the C4 definitions, containers with more than 2 components are rendered very tall with lots of whitespace.  The same diagram on the PlantUML internet server works fine.

I guess I need to run a PlantUML server in Docker or build an older version of graphviz.

Needed to edit the class name, but found that someone had already proposed a Brew formula for graphviz 2.38.  With some searching, figured out how to install it.
 

curl https://raw.githubusercontent.com/nhtzr/homebrew-core/173be0411aeccece6c4c289f15089a2e2fd5d6a7/Formula/graphviz%402.38.rb > graphviz.rb


(edit classname in file to Graphviz)

diff graphviz.rb graphviz.rb~
1c1
< class Graphviz < Formula
---
> class GraphvizAT238 < Formula

 brew install ./graphviz.rb

Note that GraphViz 2.44 has fixed this bug.

You might considere upgrade to 2.44
