<｜begin▁of▁sentence｜>### Instruction:
Given a non-chordal igraph graph created with the edges [(0, 1), (1, 2), (2, 3), (3, 0), (1, 3)], how can you use the chordal_completion function to make it chordal and confirm it with code, then display the resulting chordal graph?
### Response:
import igraph as ig

# Create a graph that is not chordal
g = ig.Graph([(0, 1), (1, 2), (2, 3), (3, 0), (1, 3)])

# Calculate the edges needed to make the graph chordal
chordal_edges = g.chordal_completion()

# Add the edges to the graph
g.add_edges(chordal_edges)

# Check if the graph is now chordal
is_chordal = g.is_chordal()
print('Is now chordal:', is_chordal)

# Plot the updated graph
ig.plot(g, vertex_label=g.vs['name'])
