<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from network.gml, can you use transitivity_undirected function in igraph to calculate the global transitivity (clustering coefficient) of the graph?
### Response:
from igraph import Graph

# Read the graph
g = Graph.Read_GML('network.gml')

# Calculate the global transitivity (clustering coefficient)
global_transitivity = g.transitivity_undirected()

# Print the global transitivity
print('The global transitivity (clustering coefficient) of the graph is:', global_transitivity)
