<｜begin▁of▁sentence｜>### Instruction:
As a special effects artist working on a new television show about a cyber-crime investigation, you want to create a realistic portrayal of the Internet and network structure. To achieve this, you have access to a dataset in the form of a GML file called as-22july06.gml, which represents the Internet Graph structure. You need to apply the RBER POTS community detection algorithm to identify different communities within the graph, representing various interconnected networks. Once the communities are detected, you need to convert the resulting NodeClustering object into a JSON representation for further analysis and visualization.
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph from file
G = nx.read_gml('as-22july06.gml')

# Apply the RBER POTS algorithm for community detection
communities = algorithms.rber_pots(G)

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

print(communities_json)
