Pong,
All of this is documented, and you can get to it by typing
sage: G.show?
Normally, the Python/Sage way of dealing with objects is to put the
object first, with a dot afterwards. Then, you can hit tab to see all
the functions available for that object, and type one ? for docs,
and ?? for source code.
Emily Kirkman has written several versions of multi-edge plotting for
graphs, but they have all gone to /dev/null due to problems with her
laptop. Currently no code exists, and she has changed gears to work on
databases.
