<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set (0, 1), (1, 2), (2, 3), (3, 0), can you use is_connected function in igraph to decide whether the graph is connected?
### Response:
from igraph import Graph

# Define edges of the graph
edges = [(0, 1), (1, 2), (2, 3), (3, 0)]

# Create the graph
g = Graph(edges=edges)

# Check if the graph is connected
is_connected = g.is_connected()

# Print result
print('The graph is connected:', is_connected)
