<｜begin▁of▁sentence｜>### Instruction:
Given two graphs with edge sets [(1, 2), (2, 3), (3, 1)] and [(4, 5), (5, 6), (6, 4)], respectively, can you use NetworkX to check whether these graphs could be isomorphic?
### Response:
import networkx as nx

# Create two graphs
G1 = nx.Graph()
G1.add_edges_from([(1, 2), (2, 3), (3, 1)])

G2 = nx.Graph()
G2.add_edges_from([(4, 5), (5, 6), (6, 4)])

# Check if the graphs could be isomorphic
result = nx.could_be_isomorphic(G1, G2)

print('The graphs could be isomorphic:', result)
