<｜begin▁of▁sentence｜>### Instruction:
As a Medical Assistant, you may need to assist the healthcare professionals in creating visual representations of patient data for presentations. One task could involve using a library like CairoPolygonDrawer to draw polygons on a Cairo context based on data from patient assessments. You may need to then ensure the results are saved as images for the visual documentation of the patient's progress.
### Response:
from igraph.drawing import CairoPolygonDrawer
import cairo

# Create a Cairo surface and context to draw on
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 800, 800)
context = cairo.Context(surface)

# Initialize the polygon drawer
polygon_drawer = CairoPolygonDrawer(context)

# Draw a triangle
points = [(100, 100), (200, 300), (100, 300)]
polygon_drawer.draw(points)

# Save the result
drawer.get_surface().write_to_png('triangle.png')
