<｜begin▁of▁sentence｜>### Instruction:
As a professional coffee roaster, you might encounter the need to create custom labels for your coffee products. Using the CairoTextDrawer, how would you draw specific text within a designated space on a label design template, ensuring that the text is word-wrapped, and then save it as an image file, such as 'coffee_label.png'? This could be a great way to add unique and informative details to your coffee packaging to enhance the overall appeal of your product.
### Response:
import igraph as ig
import cairo

# Load the graph
g = ig.Graph.Tree(3, 2)

# Create a Cairo surface to draw on
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 400, 400)
ctx = cairo.Context(surface)

# Create a text drawer object to draw text
bbox = (20, 20, 380, 380)  # Define the bounding box
font_face = 'Arial'
font_size = 12
text_drawer = ig.drawing.cairo.CairoTextDrawer(ctx, bbox, font_face, font_size)

# Set the text
my_text = 'This is a text within a bounding box'

# Draw the text using the provided CairoTextDrawer
text_drawer.draw(my_text, wrap=True)

# Save the surface to a file
surface.write_to_png('text_drawer_example.png')
