<｜begin▁of▁sentence｜>### Instruction:
As an ecotourism guide, you're leading a group on a nature walk through a beautiful forest. To ensure the safety of the group, you want to create an exact copy of the trail map you are using. How can you achieve this using the `Graph.Graph.copy` method in igraph?
### Response:
from igraph import Graph

# Create an original graph
g_original = Graph(edges=[(0, 1), (1, 2), (2, 3)])

# Use the copy method to create a duplicate of the graph
g_copy = g_original.copy()

# Print both graphs to demonstrate they are the same
print('Original graph:', g_original)
print('Copied graph:', g_copy)
