<｜begin▁of▁sentence｜>### Instruction:
Given a cycle graph with node set [0, 1, 2, 3] and edge set [(0, 1), (1, 2), (2, 3), (3, 0)], how can we apply NetworkX's greedy_color function to color the graph using the 'largest_first' strategy?
### Response:
import networkx as nx

# Create a cycle graph with 4 nodes
g = nx.cycle_graph(4)

# Apply the greedy_color function with the 'largest_first' strategy
coloring = nx.coloring.greedy_color(g, strategy='largest_first')

print('Node colorings:', coloring)
