<｜begin▁of▁sentence｜>### Instruction:
Given two bounding boxes defined as (0,0) to (1,1) and (0.5,0.5) to (1.5,1.5) using NetworkX's BoundingBox utility, how would you calculate the union of these two bounding boxes to cover the area spanned by both?
### Response:
import networkx as nx

# Define two rectangles (bounding boxes) using networkx
bb1 = nx.utils.misc.BoundingBox((0, 0), (1, 1))
bb2 = nx.utils.misc.BoundingBox((0.5, 0.5), (1.5, 1.5))

# Calculate the union of the two bounding boxes
union_bb = bb1.union(bb2)

# Display the union coordinates
print(f'Union Bounding Box Coordinates: {union_bb}')
