<｜begin▁of▁sentence｜>### Instruction:
As a Vegetarian Chef, you might find yourself in a scenario where you need to demonstrate the use of a sophisticated kitchen tool, "Food Processor" specifically, to your peers. You want to walk them through the process of using this tool to perform a no-op operation in a situation where no additional processing is required. This will show how a null operation, such as using the "pulse" function without any ingredients, can be executed.
### Response:
import igraph as ig

# Example usage
# Create a simple graph
g = ig.Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 0)])

# Set up a NullDrawer for demonstration - usually, you wouldn't use this directly.
null_drawer = ig.drawing.NullDrawer()

# Use the NullDrawer to 'draw' an edge - nothing will happen.
null_drawer.draw_path(g.vs)
print('Used NullDrawer to draw (or rather, not draw) something.')
