New description:
This adds the following method :
{{{
sage: g = graphs.PetersenGraph()
sage: g.g_ivank_string()
'10:1-8,1-9,1-10,2-5,2-7,2-10,3-4,3-7,3-9,4-6,4-10,5-6,5-9,6-8,7-8'
}}}
This string can be used for visualization at this adress :

Comment (by slabbe):
I agree with you. Returning an iframe that is hidden to the user was not a
good idea.
Although there exists other open source alternative for doing such graph
visualisation, I believe this patch is simple to code and useful for
integration in Sage (I used it myself at least two times to visualize
graphs since September). The interaction with other software (closed
source or not) is not forbidden in Sage as there exists interfaces to
Magma, Maple for instance. An interface to arborjs would be nice as well
and I am willing to referee such tickets.
I uploaded a new patch. Instead, I just return an inoffensive string. The
user may do whatever he wants with it. I think it is better like that.
Before, the earlier code returning `html(s)` was problematic and prevented
code reuse.
Needs review again!
