Drawing the graph

You can interact in all sorts of ways with the 

AGraph

 container object that you cre-

ated in the previous section, but many of those ways to interact are abstract and 

not very satisfying if you’re a visually oriented person. Sometimes it’s just nice to 

see what an object contains by looking at it. The following code displays the graph 

contained in 

AGraph

:

nx.draw(AGraph, with_labels=True)

The 

draw()

 function provides various arguments that you can use to dress up the 

display, such as modifying the node color using the 

node_color

 argument and the 

edge color using the 

edge_color

 argument. Figure 8-4 shows the graph contained 

in 

AGraph

.

FIGURE 8-4: 

Seeing what a 

graph contains 

makes it easier to 

understand.
