Yes, graphviz comes with Guile bindings.  Since they don’t provide a
Guile module you need to define a module like this:

--8<---------------cut here---------------start------------->8---
(define-module (libgv)
  #:export (digraph node edge layout render setv))

(load-extension "libgv_guile" "SWIG_init")
--8<---------------cut here---------------end--------------->8---

These bindings are not very useful for anything beyond visualizing
graphs, though.
