<｜begin▁of▁sentence｜>### Instruction:
Using the American College football team network data stored in a GML file named football.gml, can you apply the ego-networks community detection algorithm using cdlib to identify the overlapping communities centered at each node within a 1-hop radius? Also, can you provide a JSON representation of the identified communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Load the American College football team network
G = nx.read_gml('football.gml')

# Apply ego-networks community detection algorithm
# with default level (1-hop neighborhood)
communities = algorithms.ego_networks(G)

# Convert communities to json representation
communities_json = communities.to_json()
print(communities_json)
