<｜begin▁of▁sentence｜>### Instruction:
Given the 'Les Miserables' graph which you can read from a GML file named lesmis.gml, can you use the 'principled_clustering' function from the cdlib library to perform community detection with an aim to find 5 communities? And can you provide a JSON representation of the resulting communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Load Les Miserables graph
G = nx.read_gml('lesmis.gml')

# Apply the principled clustering algorithm to find 5 communities
coms = algorithms.principled_clustering(G, 5)

# Convert the clustering to a JSON object
coms_json = coms.to_json()

print(coms_json)
