<｜begin▁of▁sentence｜>### Instruction:
Given a graph G which is a cycle graph of 5 nodes with an additional edge added between nodes 1 and 3 making it non-chordal, how can you use the 'complete_to_chordal_graph' function to convert it into a chordal graph? And which new edges are added in the process?
### Response:
import networkx as nx
from networkx.algorithms.chordal import complete_to_chordal_graph

# Create a non-chordal graph G
G = nx.cycle_graph(5)
# Add an edge to make it a non-chordal graph
G.add_edge(1, 3)

# Convert the non-chordal graph to a chordal graph H
H, alpha = complete_to_chordal_graph(G)

# Print the edges of the chordal graph
print('Chordal graph edges:', H.edges())
# Print the new edges added to G to make it chordal
new_edges = set(H.edges()) - set(G.edges())
print('Edges added:', new_edges)
