<｜begin▁of▁sentence｜>### Instruction:
As an Artificial Intelligence Engineer, you are working on a project to analyze network dynamics within the political blogosphere. You have access to a graph described in a GML file named polblogs.gml, which represents the relationships between political blogs. Your task is to utilize the async_fluid community detection algorithm from the cdlib library to detect communities within this graph, with the specific requirement of identifying two distinct communities. Following this, you need to format the resulting communities in JSON format for further analysis and visualization.
### Response:
import networkx as nx
from cdlib import algorithms

# Create a graph
G = nx.read_gml('polblogs.gml')

# Apply the Async Fluid Communities detection algorithm with a desired number of communities
communities = algorithms.async_fluid(G, k=2)

# Convert the clustering to a JSON object
communities_json = communities.to_json()

print(communities_json)
