I think here's a rough way to do what you want:
* Generate a random graph G with RanomGNP, i.e. G is undirected.
Hi
I need to generate oriented graphs at random or possibly create one
from the graph generated by the function randomGNP.
Here is the definition of oriented graphs --

I am not able to do this correctly. I would be very thankful for any
help.

Is there a SAGE command that will produce a primality
certificate for a (prime) integer input?
Best regards,

implicit_plot3d raises a MemoryError when the bounding box defined by
the x,y,z min/max ranges does not contain the surface. For example,
consider the following command that plots half of a sphere:
sage: var('x, y, z')
sage: implicit_plot3d(x^2 + y^2 + z^2 - 1, (x,0,2), (y,-1,1),
(z,-1,1)).show(v
