<｜begin▁of▁sentence｜>### Instruction:
As a journalist, you've been tasked with investigating and reporting on the social dynamics within a community using network analysis. Imagine you have access to a graph representing the interactions within a social network, such as a group of people living in a small town. You are looking to employ a tool like cdlib with the pycombo function to conduct community detection, revealing distinct groups within the population. Furthermore, you're interested in obtaining the JSON representation of the resulting NodeClustering object to analyze and report on the identified communities.
### Response:
import networkx as nx
from cdlib import algorithms

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

# Apply Combo for community detection
communities = algorithms.pycombo(G, weight='weight', max_communities=None, modularity_resolution=1.0, num_split_attempts=0, start_separate=False, treat_as_modularity=False, random_seed=42)

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

print(communities_json)
<|EOT|>
