Hi,
Do you know if there’s a Processing library to make node-based tree graphs (other than the [correlation library](http://www.muehlseife.de/correlations-library/) that is unfortunaltely not P3 compatible) ?
Thanks.

Have you already tried to contact them by e-mail or Facebook for its source code? 🥺

No, I did not. Should I ?

There’s a high probability that converting that library to Processing 3.4 would be just some little fixes here and there. Nothing too complicated! 😇
So it’s worth a try to get ahold of the source code IMO. 😹

I see. But I guess it would be more about requesting permission rather than asking for the source code since we already have the possibility to access it (with a Java decompiler like JD-GUI for instance). Right ?

W/ a decompiler, everything would be a mess, b/c all labels for variables, methods, etc. would be lost! 🤢

Ok, I’ll give it a shot (contacting them).

Ah, I remember looking at Correlations [a while back](https://forum.processing.org/two/discussion/18694/correlations-library).
The strange thing is, I think Correlations was originally distributed with the source code. From the old (broken) blog post:
[http://mstest1234.blogspot.com/](http://mstest1234.blogspot.com/)
> You can download the library package **including the source code** and 3 Processing examples [here](http://www.4dcube.de/muehlseife/correlations/distribution/correlations-alpha%200.4/download/correlations-alpha%200.4.zip).
The later reposting to [correlations library |](http://www.muehlseife.de/correlations-library/) has the jar and examples, but does not include the source code, even though it is the same version number.
I’ve quickly looked inside the class files with [http://www.javadecompilers.com/](http://www.javadecompilers.com/) using the CFR decompiler, and most of the decompile is pretty clean (although a few key parts of Node.java and Graph.java are quite messy). I’ve never actually used it for a project – instead I have used GraphStream.
