<｜begin▁of▁sentence｜>### Instruction:
Given the 'Les Miserables' character network which you can read from a GML file named 'lesmis.gml', can you use the k-clique function in cdlib to perform community detection with k=4? And can you output the result in JSON format?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the Les Miserables graph from the GML file
G = nx.read_gml('lesmis.gml')

# Perform k-clique community detection with k=4
communities = algorithms.kclique(G, k=4)

# Convert the community structure to a JSON object
communities_json = communities.to_json()

print(communities_json)
