<｜begin▁of▁sentence｜>### Instruction:
Given the Internet graph stored in a gml file named as-22july06.gml, how can you visualize the communities detected by the Leiden algorithm using cdlib's plot_network_clusters function?
### Response:
from cdlib import algorithms, viz
import networkx as nx

# Create an Internet Graph from an external gml file
G = nx.read_gml('as-22july06.gml')

# Perform community detection using the Leiden algorithm
communities = algorithms.leiden(G)

# Compute the positions using the spring layout algorithm
pos = nx.spring_layout(G)

# Plot the graph with node color coding for the detected communities
viz.plot_network_clusters(G, communities, pos, figsize=(8, 8), node_size=200)
