<｜begin▁of▁sentence｜>### Instruction:
As a Quality Assurance (QA) Analyst, you are responsible for assessing and evaluating software to ensure they meet quality standards. One of your tasks involves using manual or automated testing tools to identify defects and report findings to improve user satisfaction. Imagine you are working at a technology company where you are assigned to analyze the American College football network stored in a gml file called football.gml. Your goal is to perform community detection using the AGDL algorithm available in the cdlib library. After obtaining the NodeClustering object, your next step is to convert it to JSON format and print the JSON output for further analysis and decision-making.
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from the American College football dataset
G = nx.read_gml('football.gml')

# Apply the AGDL community detection algorithm
communities = algorithms.agdl(G, number_communities=3, kc=4)

# You can also convert the NodeClustering object to JSON
communities_json = communities.to_json()

print(communities_json)
