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?
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.
