Each visualisation would probably require its own script (about as long
as graph.js for the chord diagram) because the data may need to be
prepared and mapped to SVG nodes differently.  Switching within the same
HTML document doesn’t make much sense because almost none of the SVG
elements can be reused.

The data structure I’m building up with the emit-* procedures should be
reusable, though.  (This isn’t very pretty because I’m emitting code to
produce the data structure; it’s not a simple JSON description of the
graph.)

Hmm, so each time I run “guix graph” the resulting HTML document ends up
in the store.  I was hoping to avoid this, actually, but since the HTML
file is pretty small (when d3.js is not embedded) I guess it’s fine.
