<｜begin▁of▁sentence｜>### Instruction:
Given the Word adjacencies graph which you can read from a GML file named adjnoun.gml, can you use the Girvan–Newman algorithm in cdlib to perform community detection? And can you generate a JSON representation of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms

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

# Apply Girvan-Newman algorithm to detect communities
communities = algorithms.girvan_newman(G, level=1)

# Generate JSON representation of the communities
communities_json = communities.to_json()

print(communities_json)
