<｜begin▁of▁sentence｜>### Instruction:
As a Blockchain Developer, you have been tasked with determining the union of two bounding boxes and printing the coordinates of the resulting bounding box. The first bounding box has vertex coordinates at (10,10) and (30,30), and the second bounding box has vertex coordinates at (20,20) and (50,50). Using the BoundingBox.union function in igraph, calculate the union of the two bounding boxes and print the coordinates of the resulting bounding box.
### Response:
from igraph.drawing.utils import BoundingBox

# Create two bounding boxes
bbox1 = BoundingBox(10, 10, 30, 30)
bbox2 = BoundingBox(20, 20, 50, 50)

# Take the union of the two bounding boxes
bbox_union = bbox1.union(bbox2)

# Print the coordinates of the union bounding box
print(f'Union BoundingBox: {bbox_union}')
