I am interested in modifying the way Sage draws Graphs and,
especially, multi-edged graphs.
Emily Kirkman seems to be working on that point but her blog doesn't
give any information on recent success.
I also want to use Matplotlib to draw graphs. Should i start from

i'am a little bit confused while analysing Sage Python packages and

when one types

plot_f_exp.show()
what happens exactly in the plot() part ?

hi,
when one uses plot_points and plot_division in a plot command, there
is something misleading (imho) :
plot_points = 3 gives exactely 3 points in the initial plot (before refinement)
plot_division = 5 can add up to 6 points to the original 3
It is not obvious also that this number of

While we continue to add tests to the notebook code, there are some
things that we just can't test directly in Python such as browser
