<｜begin▁of▁sentence｜>### Instruction:
As a mental health nurse, let's consider a scenario in which you are tasked with conducting an analysis of the social network among patients in a mental health support group. You want to use the CONGA (Cluster-Overlap Newman Girvan Algorithm) method to identify and analyze the different community structures within the patient network. Additionally, you need to provide a JSON representation of the detected community structure for further assessment and support planning.
### Response:
import networkx as nx
from cdlib import algorithms

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

# Run the CONGA community detection algorithm
communities = algorithms.conga(G, number_communities=3)

# Export the NodeClustering object to JSON
community_json = communities.to_json()

print(community_json)
