Graphviz dependency

[paulvi]

It would be nice to install Graphviz automatically,
or use it embeddable alternatives

From https://modeling-languages.com/interview-plantuml/

There is now a weird solution that does work: using a port to Javascript of GraphViz and running it on the J2V8 engine. I have also partially translated GraphViz source from C to Java (which is a huge and painful task). This allows PlantUML to fully run in pure Java environment.

J2V8 is https://github.com/eclipsesource/j2v8
Where is GraphViz .js script?

Graphviz (not required)

This integrate an old version of viz.js. The reason why it was never updated is simply because the integration is surprisingly solid and the performance is stunning (never change a running system if you don't need to ;-). we can update that to a new version if needed, but I would like to test that properly before, as the already available integration runs here since years without any problems; even with fairly big diagrams.
