I found the mailing list address with a bit of Ducking around:
https://duckduckgo.com/?q=graphviz-devel+mailing+list

Unfortunately, this list doesn't seem to exist anymore, because my
e-mail bounced.

I cannot download the source code, because that is/was hosted on
graphviz.org as well.  The header files do not contain contact
information of a developer, so I guess we have to wait until it comes
back online.

Or do you think we can move along now and update the graphviz-guile
package whenever we get it in upstream?  I am definitely interested in
adding an option to directly output an SVG in the graph subcommand, for
which graphviz-guile is a prerequisite.

Thanks for your time!

Kind regards,
