<｜begin▁of▁sentence｜>### Instruction:
Given the Power Grid Graph which you can read from a GML file named power.gml, can you use the 'principled_clustering' community detection algorithm in CDlib to identify communities? How would you represent the resulting clustering as a JSON object?
### Response:
import networkx as nx
from cdlib import algorithms

G = nx.read_gml('power.gml')
coms = algorithms.principled_clustering(G, 2)

# To get the JSON representation of the clustering
coms_json = coms.to_json()
print(coms_json)
