<｜begin▁of▁sentence｜>### Instruction:
As an Infectious Disease Specialist, let's consider a scenario where you're tasked with visually representing the spread of a new pathogen on a geographic map using Cairo, a graphics library. You need to display a triangular marker at specific coordinates to indicate outbreak locations.

How would you utilize Cairo's plotting capabilities to draw an upright triangle centered precisely at the given coordinates without applying any stroke or fill? Additionally, how would you complete the action by incorporating the stroke or fill to enhance the visual representation of the outbreak?
### Response:
from igraph.drawing import Plot
from igraph.drawing.shapes import UpTriangleDrawer

# Assuming 'context' is a Cairo context on which we want to draw
# Providing the coordinates for the triangle's center

center_x, center_y = 100, 100

# Initiate a drawer instance
triangle_drawer = UpTriangleDrawer()

# Call the draw_path method
triangle_drawer.draw_path(context, center_x, center_y, 20)

# To fill or stroke the triangle, you can use the context methods
context.fill()
# OR
context.stroke()
