<｜begin▁of▁sentence｜>### Instruction:
Given the 'Les Miserables' graph, which you can read from a GML file named lesmis.gml, can you use the Louvain algorithm from the cdlib library to perform community detection? And can you convert the resulting community structure into a JSON object?
### Response:
import networkx as nx
from cdlib import algorithms

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

# Apply the Louvain community detection algorithm
communities = algorithms.louvain(G, weight='weight', resolution=1.0)

# Convert the community structure to JSON
json_communities = communities.to_json()
print(json_communities)
