<｜begin▁of▁sentence｜>### Instruction:
Assuming you have a sample text that you need to render on a graphical Canvas using Cairo in Python, how can you calculate the text layout with reference points starting at specific coordinates (e.g., x=10, y=10), and ensure the text wraps if it exceeds a certain width (e.g., 200 pixels)? The text alignment should be 'left' and 'top'.
### Response:
import igraph as ig

# Sample text to estimate layout
sample_text = 'This is a sample text.'

# Create a Cairo surface and context
cnv = ig.plot(ig.Graph(), bbox=(600, 400), target=None).cairo

# Create a TextDrawer
drawer = ig.drawing.text.CairoTextDrawer(cnv, halign='left', valign='top')

# Set the font, size, and text for the drawer
drawer.set_font_face('Arial')
drawer.set_font_size(12)
drawer.set_text(sample_text)

# Calculate text layout, here assuming we want to start at x=10, y=10
layout = drawer.get_text_layout(x=10, y=10, width=200, wrap=True)

# Print text layout positions and lines
for x, y, line in layout:
    print(f'Position: ({x}, {y}) - Text: {line}')
