<｜begin▁of▁sentence｜>### Instruction:
Given a graph with nodes labeled from 1 to 5 and edges connecting them as follows: (1,2), (1,3), (1,4), (3,4), (3,5), and (4,5), what is the radius of the graph? The radius is the minimum distance from any node to the farthest node it can reach.
### Response:
import networkx as nx

# Example graph
G = nx.Graph([(1, 2), (1, 3), (1, 4), (3, 4), (3, 5), (4, 5)])

# Calculate the radius of the graph
radius = nx.radius(G)

# Output the radius
print('The radius of the graph is:', radius)
