Maybe it make sense to expand it a bit at least for GCs (https://pagure.io/fork/tkopecek/koji/blob/9a6e8af1e11d049d0dd840b35eff0558baab88a4/f/docs/source/koji_structure1.png)

Maybe those kojid/kojivmd kojira/koji-gc are above the lien in this "zoom", but CGs are nowadays a vital part of eco-system.

I think so, but that could also be a follow up. I'm not certain that CGs should be presented as quite so parallel to the build daemons.

Do we have to convert to png? Can't most browsers handle svg? We'd probably need to convert to "simple" svg instead of the inkscape one.

svg seems to work: https://pagure.io/fork/tkopecek/koji/commits/tk-pr1375

I've amended this pull request to only use the SVG and skip the PNG.

As far as adding more daemons into a diagram, I think that would be useful to illustrate as separate diagrams. I wanted this one to be something that users can look at to understand Koji at a high level.
