<｜begin▁of▁sentence｜>### Instruction:
As a building designer, I often consider the structural integrity of my designs. When working on a new project, I need to ensure that the architectural elements are positioned in such a way that they do not create any weak points in the overall structure. In the same way, when working with a network graph, I need to check if it is chordal, meaning that there are no induced cycles of length four or more. This is critical for optimizing the connectivity and efficiency of the network. Therefore, I want to know if the igraph's is_chordal function can be used to determine if a given graph, such as Zachary's karate club graph, is chordal.
### Response:
import igraph as ig

# Assume G is an igraph Graph object
g = ig.Graph.Famous('Zachary')
# Check if the graph is chordal
is_chordal = g.is_chordal()
print('Is the graph chordal?', is_chordal)
