<｜begin▁of▁sentence｜>### Instruction:
Given the graph of books about US politics which you can read from a GML file named polbooks.gml, can you use the MULTICOM algorithm in cdlib with a specified seed node to perform community detection and then generate and print a JSON representation of the detected communities?
### Response:
import networkx as nx
from cdlib import algorithms

# Read the graph
G = nx.read_gml('polbooks.gml')

# Perform community detection using MULTICOM algorithm with a specified seed node
coms = algorithms.multicom(G, seed_node=0)

# Save the resulting communities to JSON
communities_json = coms.to_json()
print(communities_json)
