<｜begin▁of▁sentence｜>### Instruction:
As a biologist studying living organisms and their interactions with the environment, imagine you're working on a project tracking the movement patterns of a group of animals within a defined area. You've collected data on the coordinates of various points where these animals have been observed. Now, you need to determine the smallest rectangular region that encompasses all these points, providing a safe boundary for further analysis. Additionally, you want to calculate the coordinates of the bottom-left and top-right corners of this bounding box. To achieve this, you could utilize the `networkx` library in Python, specifically leveraging its functionalities for graph layout analysis.
### Response:
from igraph import Graph, Layout

# Assume we have predefined vertex positions in 'layout'
layout = Layout([(0, 1), (2, 3), (4, 5), (6, 7)])

# Calculate the bounding box with a border of 1
bbox = layout.bounding_box(border=1)

# Getting the coordinates of the bounding box
lower_left = bbox.lower_left
upper_right = bbox.upper_right

print('Lower Left Corner:', lower_left)
print('Upper Right Corner:', upper_right)
