How do I make resulting output sharper?

[Martinsos]

Hi, thanks for this great library!

I am building the module graph with following command:

graphmod --quiet --prune-edges $PROJECT_ROOT/src/**/*.hs | dot -Gsize=20,20! -Tpng -o module-graph.png

The PNG I get as a result is looking good, with two problems however:

1. Node names are pretty small, so zooming in is required.
2. Resolution is not high enough to be able to read the node names clearly even after zooming in.

Therefore, I would love to:

1. Increase the font size of nodes.
2. Increase the resolution of the image itself.

I tried increasing dot -Gsize= to 40,40 and that helps with resolution, but I have no idea how to increase the font size. Any help is welcome!

I also tried doing dot -Nfontsize=20, but that had no effect.

What I learned since asking this question is following:

1. I probably just need to figure out how to make dot show the graph as I want, so this probably has nothing to do with graphmod itself.
2. I can use -Gsize=N,N to increase resolution, I can use -Nfontsize=N to increase node label font size. There are different layouts dot can use, however fontsize doesn't seem to work for me if I use it with dot layout, which is the only layout that gives good results for this use case. So I am kind of stuck there. I managed to get fontsize working for other layouts, but for dot layout, it gets ignored if it is bigger than ~12. I can put it to smaller, that makes it smaller, but anything beyond ~12 seems to be capped to 12 or something close to 12. I tried also doing -Nfixedsize=false but that didn't help.

I realize now this has nothing to do with graphmod, so feel free to close the issue -> I will still leave it open a bit, in case you can help me easily. Also, I am guessing some other people who don't know graphviz might also encounter this issue, so it might be useful for them to have this issue exist.
