<｜begin▁of▁sentence｜>### Instruction:
Given the triad name '030T', which describes one of the 16 possible triad configurations in a directed graph of three nodes, create and visualize the corresponding triad graph using NetworkX. How is this triad graph structured with nodes labeled 'a', 'b', and 'c'?
### Response:
import networkx as nx

# Use the triad_graph function with a valid triad name
triad_name = '030T'
triad = nx.triad_graph(triad_name)

# Print the edges of the triad graph
print(triad.edges())

# Draw the triad graph (requires matplotlib)
try:
    import matplotlib.pyplot as plt
    nx.draw(triad, with_labels=True)
    plt.show()
except ImportError:
    print('matplotlib is not installed')
