<｜begin▁of▁sentence｜>### Instruction:
Suppose you want to create a visualization of a rhombus shape in a graph drawing, and you are using the 'igraph' library in Python. How would you use the 'DiamondDrawer.draw_path' method from 'igraph' to outline the path for a rhombus at the center of the drawing area with a given size, without actually stroking or filling it?
### Response:
from igraph.drawing import Plot
from igraph.drawing.shapes import DiamondDrawer
from cairo import Context, ImageSurface, FORMAT_ARGB32

# Create a new surface and context for Cairo drawing
surface = ImageSurface(FORMAT_ARGB32, 200, 200)
context = Context(surface)

# Initialize the DiamondDrawer with the given context
diamond_drawer = DiamondDrawer(context)

# Calculate the center and the size of the rhombus
center_x, center_y = 100, 100
size = 50

# Draw the path for a rhombus shape
diamond_drawer.draw_path(center_x, center_y, size)

# Optionally, stroke or fill the path
d = 0.1 * size  # a small delta to outline the shape
context.set_line_width(d)
context.stroke_preserve()
context.set_source_rgba(1, 0, 0, 0.8) # Red with transparency
context.fill()

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