<｜begin▁of▁sentence｜>### Instruction:
As an event planner organizing a conference, you are using a network visualization tool to display the connections among speakers. You want to adjust the layout dimensions of the graph to fit better within the event program brochure. The network was created using the Erdős-Rényi model with 5 nodes and 10 edges. You are using the CairoMatrixDrawer class from the igraph's drawing module to adjust the bounding box of the drawing area from (20, 20, 400, 400) to (50, 50, 450, 450) to ensure the layout fits appropriately within the brochure. Can you guide me in making this adjustment?
### Response:
from igraph.drawing import CairoMatrixDrawer

# Suppose we have a graph to draw
g = Graph.Erdos_Renyi(n=5, m=10)

# Create an instance of CairoMatrixDrawer
drawer = CairoMatrixDrawer(surface=None, bbox=(20, 20, 400, 400))

# Define the new bounding box size for the drawing area
drawer.bbox = (50, 50, 450, 450)

# Now, when using the drawer to draw the graph, it will use the updated bounding box
drawer.draw(g)
