<｜begin▁of▁sentence｜>### Instruction:
As a fashion designer, you have been tasked with evaluating the structural integrity of a complex pattern for a new clothing line. One method to determine this is by using a specialized tool called the is_chordal function in graph_data.gml analysis, which can help assess whether the pattern is chordal or not. Understanding the chordality of the pattern is vital for ensuring that it is both aesthetically pleasing and functionally sound.
### Response:
from igraph import Graph

# Load the graph from a file
g = Graph.Read_GML('graph_data.gml')

# Check if the graph is chordal
is_chordal = g.is_chordal()

# Output the result
print('Is the graph chordal?', is_chordal)
