<｜begin▁of▁sentence｜>### Instruction:
As a Life Cycle Assessment Specialist, you have been tasked with evaluating the environmental impacts of a network of 5 interconnected industrial processes. To save this network in Python pickled format, you would use the "write_pickle" function provided by the igraph API to store the graph as a file named 'full_graph.pkl'.
### Response:
import igraph as ig

# Create a full graph with 5 vertices
g = ig.Graph.Full(5)

# Save the graph to a pickle file
g.write_pickle('full_graph.pkl')

# For demonstration, read back the graph from the pickle file
g2 = ig.Graph.Read_Pickle('full_graph.pkl')
print(g2)
