You can graph the OS derivation like this:

  guix graph -t derivation $(guix system build -d config.scm)

‘dot’ takes ages to process it and the result is too big to be of any
use (it might be less bad with use an interactive graph navigation tool
like Tulip).

Otherwise there’s also ‘guix system {extension,shepherd}-graph’.

What info would you like to see on the graph?
