How can I draw a graph using networkx without explicitly calling matplotlib?

I am making interactive worksheets in Jupyter Notebook, introducing people to NetworkX. Suddenly, the nx.draw() command is not creating an output of a graph. It was working fine before, and I haven't changed anything about the code I was using. For example, one block of code that was working fine before was:

import networkx as nx

G2 = nx.Graph()

G2.add_nodes_from([1,2,3,4,5,6,7])

edgelist = [(1,4),(1,6),(1,7),(2,5),(2,6),(3,7),(4,6),(4,7),(5,7),(6,7)]
G2.add_edges_from(edgelist)

nx.draw_networkx(G2, with_labels=True, node_color = 'y') 

Now, no errors come up, but neither does a graph. I have looked and seen that other people fixed this issue bu using plt.show() but I don't understand why I suddenly need to include that when I didn't have to before. Does anyone know a way I can avoid importing matplotlib and using the plt.show() command?

Perhaps the issue is to do with some other package I have or something to do with jupyter notebook?

EDIT: It has been pointed out to me that matplotlib is a package dependency so technically there is no way of drawing a graph in networkx without using matplotlib. I understand that, but is there a way to do it without explicitly calling matplotlib?
