<｜begin▁of▁sentence｜>### Instruction:
Given a simple igraph Graph object, how would you initialize a custom graph drawer that utilizes the NullDrawer class to perform 'no operation' on a drawing context?
### Response:
import igraph as ig

class CustomGraphDrawer(ig.drawing.GraphDrawer):
    def draw(self, context, bbox):
        # Any custom drawing code can go here, this example uses NullDrawer
        drawer = ig.drawing.shapes.NullDrawer()
        # Since NullDrawer does nothing, the below line has no effect
        drawer.draw_path(context, [(0, 0), (1, 1)])

# Create a simple igraph Graph
g = ig.Graph.Full(3)

# Initialize the custom GraphDrawer
my_drawer = CustomGraphDrawer()

# Draw the graph placeholder
my_drawer.draw(None, None)
