<｜begin▁of▁sentence｜>### Instruction:
Given a barbell graph created by connecting two complete graphs of 3 nodes each with no nodes in between (creating a graph with two 'bells'), how can you bisect the graph using NetworkX's spectral_bisection function?
### Response:
import networkx as nx

# Create a barbell graph
G = nx.barbell_graph(3, 0)

# Perform spectral bisection on the graph
bisection = nx.spectral_bisection(G, weight='weight', normalized=False, tol=1e-8, method='tracemin_pcg', seed=None)

print('Bisection of nodes:', bisection)
