<｜begin▁of▁sentence｜>### Instruction:
As a networkx expert, I can rephrase the question as: "When working with a networkx graph, if a node has zero edges connected to it, is it considered an isolated node?"
### Response:
from matplotlib.patches import Rectangle

# Create a rectangle
rect = Rectangle((0, 0), 0, 0) # width and height are both zero

# Check if the rectangle is empty
is_empty = rect.isempty()

print(f'Rectangle is empty: {is_empty}')
