<｜begin▁of▁sentence｜>### Instruction:
Given a star graph with a central node connected to 3 other nodes, how can we generate its line graph and what are the edges of the resulting line graph?
### Response:
import networkx as nx

# Create a star graph with 4 nodes
G = nx.star_graph(3)

# Generate the line graph from G
L = nx.line_graph(G)

# Print the edges of the line graph
print(sorted(map(sorted, L.edges())))  # makes a 3-clique, K3
