<｜begin▁of▁sentence｜>### Instruction:
Sure, a practical scenario where this question could arise is during the development of a map visualization application. For instance, a developer may be working on a feature to render a graph network within a specific bounding box using the `igraph` library with a Cairo context for drawing. In this context, the developer may seek guidance on initializing a `CoordinateSystem` with the given bounding box size for efficient graph rendering.
### Response:
from igraph.drawing import Plot
from igraph.drawing.coord import CoordinateSystem

# Define the bounding box which determines the area covered by the plot
bbox = (0, 0, 300, 300)  # Specifying a box starting at (0,0) with a width and height of 300

# Initialize a Cairo Plot
plot = Plot(surface=None, bbox=bbox)

# Access the Cairo context
context = plot.ctx

# Use the CoordinateSystem to setup the drawer with the context and bbox
coordinate_system = CoordinateSystem(context, bbox)

# The CoordinateSystem is now ready to be used with the Cairo context.
