Comment (by slabbe):
One more point. This does not affect the result of plot:
{{{
sage: import sage.graphs.graph_plot
sage: g = graphs.PetersenGraph()
sage: sage.graphs.graph_plot.DEFAULT_SHOW_OPTIONS['figsize'] = 20
sage: g.plot()
sage: sage.graphs.graph_plot.DEFAULT_SHOW_OPTIONS['figsize'] = 2
sage: g.plot()
}}}
One may say it is because I should use {{{DEFAULT_PLOT_OPTIONS}}} instead.
But it is not the case. As the following is not affected by changing
{{{DEFAULT_PLOT_OPTIONS}}} :
{{{
sage: import sage.graphs.graph_plot
sage: g = graphs.PetersenGraph()
sage: sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['figsize'] = 2
sage: g.plot()
sage: sage.graphs.graph_plot.DEFAULT_PLOT_OPTIONS['figsize'] = 20
sage: g.plot()
}}}
Hence, I believe the documentation at the start of the file
{{{graph_plot.py}}} should contain at least one example using
{{{DEFAULT_PLOT_OPTIONS}}} and one example using
{{{DEFAULT_SHOW_OPTIONS}}}. As a user I want to understand why there are
two such dict and which one I should use.
