Filter variables in model_graphviz

[ricardoV94]

@lucianopaz suggested that we could could filter variables similar to the var_names keyword in arviz, so that we plot subsets of the model graph. This should be straightforward with some simple Aesara graph manipulation prior to calling the main function in model_graphviz

I think that could work out of the box with the filtering based on varnames

Hi @ricardoV94 and @michaelosthege, I am happy to take this task.

Thanks @danhphan!

Just a heads up, this one will require a bit of exploration. We know what we want the behavior to be like, but we don't know exactly how to achieve it just yet.

Let us know if you manage to get something working, and if not, what did you try so we can help.

Hi, yes sure, I will do some exploration first. This is a good opportunity to learn model_graphviz and arviz as well 😄

Hi, as this issue is going to be solved in #5527, I will focus on other tasks then :). Thanks

Thanks @danhphan for pointing out the duplicate.
I'm going to close this issue in favor of #5527 (because that one is more concrete in its description).

Regarding the who's working on it (cc @danhphan @soma2000-lang), I wrote it in other issues as well: We don't usually take reservations for issues.
IMO Anybody who wants to resolve an issue should just check if there's already a PR about it and if not open a (draft) pull request to get it done. Any (small) issue that doesn't have a corresponding PR yet can be considered up for grabs. Also those where someone might have been assigned a long time ago.
