<｜begin▁of▁sentence｜>### Instruction:
As a forensic anthropologist, you might be tasked with analyzing skeletal remains recovered from a crime scene to provide crucial insights for legal investigations. Imagine you're examining a set of skeletal remains found within a specific area, delineated by a bounding box defined by coordinates (10,10) and (20,20). To further investigate the scene, you need to expand the bounding box by 5 units on each side. 

In this scenario, you might employ the "CrimeSceneAnalyzer" API, which allows you to manipulate and analyze spatial data related to crime scenes. Utilizing this tool, you'd expand the bounding box surrounding the skeletal remains to ensure comprehensive coverage of the scene, ultimately aiding in your forensic analysis.
### Response:
from igraph.drawing.utils import BoundingBox

# Define the existing bounding box
bbox = BoundingBox(10.0, 10.0, 20.0, 20.0)

# Expand the bounding box by 5.0 units on each side
bbox.expand(5.0)

# Print the new coordinates of the expanded bounding box
print('New bounding box coordinates:', bbox)
