<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph with the edge set [(0, 1), (1, 2)], can you use the convergence_field_size function in igraph to determine the size of the convergence field?
### Response:
import igraph as ig

# Create a graph
g = ig.Graph(edges=[(0, 1), (1, 2)], directed=True)

# Example usage of convergence_field_size - Assuming the method is related to the convergence of fields in a graph
# This method doesn't have documentation, but we can speculate that it could return a size
# related to convergence in some dynamic process.
field_size = g.convergence_field_size()

# Print the 'size' of the convergence field
print('Convergence field size:', field_size)
