<｜begin▁of▁sentence｜>### Instruction:
Given that you have a rectangle with its bottom-left vertex at (10, 10) and top-right vertex initially at (30, 30), if you want to set the width of this rectangle to 50 units by adjusting the right edge, how can you do this using the Rectangle.width attribute in igraph?
### Response:
from igraph.drawing.utils import Rectangle

# create a rectangle with bottom-left vertex at (10, 10)
r = Rectangle(10, 10, 30, 30)

# print the current width of the rectangle
print('Current width:', r.width)

# set the width of the rectangle to 50 by adjusting the right edge
r.width = 50

# Print the new width of the rectangle
print('New width:', r.width)
