<｜begin▁of▁sentence｜>### Instruction:
As a Web Content Manager responsible for managing and updating the content of an online platform dedicated to network analysis tools, you are tasked with presenting a new feature to the users. The system allows users to upload network data in GML format and conduct community detection using various algorithms. One user inquires about the Walktrap algorithm's availability for community detection using the cdlib API. The user also requests assistance in displaying the node-to-community mapping after the detection process. How would you address this query while upholding accuracy and relevance on the website?
### Response:
import networkx as nx
from cdlib import algorithms

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

# Perform community detection using the walktrap algorithm
communities = algorithms.walktrap(G)

# Convert the communities to a NodeClustering object
node_clustering = communities.to_node_community_map()

# Output the result
print(node_clustering)
