<｜begin▁of▁sentence｜>### Instruction:
Given a graph with the edge set [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0), (0, 2), (1, 3)], how can you calculate a greedy vertex coloring using igraph's vertex_coloring_greedy function, and what is the resulting coloring?
### Response:
import igraph as ig

# Create a graph with a known structure
edges = [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0), (0, 2), (1, 3)]
g = ig.Graph(edges=edges)

# Calculate a greedy vertex coloring for the graph
coloring = g.vertex_coloring_greedy()

# Print the coloring result (each color is represented by a list of vertex indices)
print('Vertex coloring:', coloring)
