Replying to [comment:19 slabbe]:
> For me, I think the confusion comes from the fact that using plot
actually opens the png. I like it if plot returns the Graphics object
without opening any png and show returning None and openning the png.
Actually, plot never returns the rendered graphics object. What happens
when you ''don't'' assign any variable to plot like
{{{
a = plot(...) # assigning the output of plot to variable a
}}}
then the `_repr_()` method of the `Graphics` class is called. This is
similar to the way the `print` function in Sage works. The `_repr_` method
then implicitly calls show and your graph gets rendered and displayed.
