I was trying to plot some graphs in SMC. However, even the first example given in Graph Plotting doesn't work. I only got an empty output. The following is the example i was trying.

sage: G = graphs.WheelGraph(15)

sage: G.plot()

What am I missing in my example?

P.S.: Yes. The example works in Sage worksheets, however, it doesn't work in iPython notebook. How to make it work in iPython notebook?

Nothing missing; the code works in a [Sage Cell Server](https://sagecell.sagemath.org/).

Try the following code in ipython in SMC to load the sage commands and the networkx library. Then, you can see the graph.

from sage.all import *
import networkx as nx
G = graphs.WheelGraph(15)
H=G.networkx_graph()
nx.draw(H)
plt.savefig("simple_path.png")
plt.show()

I'm afraid the code cannot return what I expected. Yes, it returns a Wheel graph with 15 vertices. But the graph drawn there is ugly. Thank you for sharing anyway.

I get the same graph in iPython as in Sage. There are some formatting options for graphs that can be used in Sage. I imagine that networkx has similar options that might allow you to get the format that you want.
