[bug#61527] [PATCH] Add edgelist graph backend

Is “CSV edge list” some sort of a standard format, or is it more of an
idea you came up with?

The patch LGTM but we’ll need a couple more things:

  1. Maybe emitting extra metadata as Simon suggested.

  2. Adding documentation under “Invoking guix graph”.  In particular,
     it’d be nice to have an example showing how to query the generated
     CSV with igraph.

  3. Ideally a full patch with commit log as generated with ‘git
     format-patch’.  :-)

Could you send an updated patch?

Thank you!

Ludo’.
