<｜begin▁of▁sentence｜>### Instruction:
Given two igraph BoundingBox instances `bbox1` and `bbox2` with the same dimensions, and a third BoundingBox `bbox3` with different dimensions, can you use the `__eq__` method to check if `bbox1` and `bbox2` are equal, and if `bbox1` and `bbox3` are not equal?
### Response:
import igraph as ig

# Create two bounding box instances
bbox1 = ig.drawing.BoundingBox(100, 100)
bbox2 = ig.drawing.BoundingBox(100, 100)
bbox3 = ig.drawing.BoundingBox(150, 150)

# Check if two bounding boxes are equal
are_equal = bbox1 == bbox2  # Should return True
are_not_equal = bbox1 == bbox3  # Should return False

print('Bounding Box 1 and 2 are equal:', are_equal)
print('Bounding Box 1 and 3 are not equal:', are_not_equal)
