DOC: Scale networkx layout and fix graphviz init in doc build

[MridulS]

I was about to point someone towards hvplot docs for networkx and saw that the notebook build is broken https://hvplot.holoviz.org/en/docs/dev/user_guide/NetworkX.html for pygraphviz (and rest of the notebook).

graphviz from conda-forge should run the post link dot -c but I'm not sure why it isn't doing it. (maybe pixi ignores it?)

I also scaled the layout for shell layout from networkx so it's looks prettier while comparing the two layouts.

Thank you for the lovely PR.

I ran the docs build locally, and it seems fine to me, but you never know about the CI gods.

For future reference, this is what is shown on the current homepage

Hi @MridulS, thanks for looking into that! Good guess, pixi doesn't run the post link script by default, Simon is taking care of fixing that in our global action github.com/holoviz-dev/holoviz_tasks/pull/46. Once merged, we'll undo the "dot" changes in this PR, but of course keep your layout changes 👍

Nice to hear that! Do you have any feedback on the networkx plotting API implemented in hvPlot? I have to say I haven't used it much myself, if at all, so I can't really say how good/practical/robust it is.

Nothing major, just wanted to point someone who asked for bokeh + networkx :)
