<｜begin▁of▁sentence｜>### Instruction:
Given an igraph Graph object already created and named 'g', you have to find the convergence field size of the graph using the convergence_field_size method in igraph. How would you do it?
### Response:
from igraph import Graph

# Assuming we already have an igraph Graph object 'g'
# which you can instantiate as per your graph data
# g = Graph.Read('your_graph_file.gml') or any other igraph-supported format

# Get the convergence field size (assuming this method is now documented and returns such a value)
convergence_field_size = g.convergence_field_size()

print('Convergence Field Size:', convergence_field_size)
