<｜begin▁of▁sentence｜>### Instruction:
Given a graph with an edge set [(0, 1), (0, 2), (1, 2), (2, 3)], compute its normalized Laplacian matrix using NetworkX.
### Response:
import networkx as nx
G = nx.Graph()
G.add_edges_from([(0, 1), (0, 2), (1, 2), (2, 3)])
laplacian = nx.normalized_laplacian_matrix(G)
print(laplacian.toarray())
