<｜begin▁of▁sentence｜>### Instruction:
Given an undirected graph with edges [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0)], can you calculate and print the radius of the graph?
### Response:
from igraph import Graph

# Define a simple undirected graph
edges = [(0, 1), (1, 2), (2, 3), (3, 4), (4, 0)]
g = Graph(edges)

# Calculate the graph radius
radius = g.radius()
print('Radius of the graph:', radius)
