Description
As reported there https://groups.google.com/d/topic/sage-edu/ivWea0Gk3_Q/discussion
By the way, nobody would expect this {{{ sage: graphs.CompleteBipartiteGraph?(3,2).is_circular_planar() True }}}
The same way that nobody would expect Sage to return "True" when is_planar
is called on K_5
. And this was one of the doctests -_-

OK, that was also my conclusion. :-(
But that doesn't affect the validity of this patch.

Could you please check that this patch is correct ? I updated this cursed reference [2]
to respect Sphinx' format.

Replying to jdemeyer:
dochtml.log:[graphs ] /mazur/release/merger/sage-5.10.rc0/local/lib/python2.7/site-packages/sage/graphs/generic_graph.py:docstring of sage.graphs.generic_graph.GenericGraph.is_circular_planar:47: ERROR: Unknown target name: "2".
Aaargh, I had expected ./sage -docbuild reference html
to summarise any errors encountered at the end. But I guess this is not the case. Luckily, I meanwhile discovered ./sage -docbuild reference/graphs html
. The rest is still the same, so OK for me.

Seems OK. Everything works as I expect it to work, the tests pass and the documentation is clearer. The only thing I was wondering about is the reference which says: '[Online] Available: soon!' You might not now whether this is available in the meantime and where? I couldn't find anything.
