<｜begin▁of▁sentence｜>### Instruction:
Given a non-chordal graph represented as a cycle graph with 4 nodes, use chordal_completion method in NetworkX to make the graph chordal, and confirm if the graph is now chordal.
### Response:
import networkx as nx

# Create a non-chordal graph
G = nx.cycle_graph(4)

# Find the edges that need to be added to make the graph chordal
fill_edges = nx.find_graph_chordal_completion(G)

# Add the edges to the graph
G.add_edges_from(fill_edges)

# Now G is chordal
print(nx.is_chordal(G))  # Should print True
