<｜begin▁of▁sentence｜>### Instruction:
As a Green Architect, you have been tasked with analyzing the network structure of a community of political bloggers to understand their interactions and identify cohesive groups within the community. You have access to the Political blogs dataset, which is stored in a GML file named polblogs.gml. To achieve this, you are interested in using the CDlib Greedy Modularity community detection algorithm. Additionally, once the communities are detected, you need to convert the resulting community structure into a JSON object for further analysis and visualization.
### Response:
import networkx as nx
from cdlib import algorithms

# Creating a sample graph from the Political blogs dataset
g = nx.read_gml('polblogs.gml')

# Applying the Greedy Modularity Community detection algorithm
coms = algorithms.greedy_modularity(g)

# Convert the community structure to a JSON object
coms_json = coms.to_json()

print(coms_json)
