<｜begin▁of▁sentence｜>### Instruction:
Given a graph with edge set [(0, 1), (1, 2), (2, 3), (3, 0)], how can AbstractCairoDrawer.AbstractCairoDrawer.bbox be utilized in igraph alongside Cairo to draw the graph within a custom bounding box?
### Response:
import igraph as ig
import cairo

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

# Define the size of the image
width, height = 300, 300

# Create a Cairo Image Surface to draw on
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height)
ctx = cairo.Context(surface)

# Choose a layout for the graph
layout = g.layout('auto')

# Create and configure a plot object
plot = ig.Plot(surface, bbox=(0, 0, width, height), background='white')
plot.add(g, layout=layout)

# Adjust the bounding box
plot.bbox = (50, 50, 250, 250)

# Save the plot to a file
plot.save('custom_bbox_graph.png')
