<｜begin▁of▁sentence｜>### Instruction:
{'description': 'Given an undirected barbell graph created with `nx.barbell_graph(4, 2)`, can you identify the articulation points, or cut vertices, using NetworkX?', 'data': 'A barbell graph consisting of two complete graphs of 4 nodes connected by a path with 2 nodes.', 'problem': 'The task is to find all the articulation points (nodes whose removal increases the number of connected components) in the given barbell graph.'}
### Response:
import networkx as nx

# Create an undirected graph
G = nx.barbell_graph(4, 2)

# Identify the articulation points of the graph
articulation_pts = list(nx.articulation_points(G))

print('Articulation points:', articulation_pts)
