<｜begin▁of▁sentence｜>### Instruction:
As a statistician specializing in data visualization, you're tasked with rendering textual information on a graphical canvas using Python's Cairo library. In this scenario, you have a sample text that needs to be laid out on the canvas with specific reference points starting at coordinates x=10 and y=10. Additionally, you need to ensure that the text wraps if it exceeds a certain width, for example, 200 pixels. The desired text alignment is 'left' and 'top'.

Your expertise in statistical methods and software tools enables you to calculate the layout of the text accurately, considering its starting coordinates and wrapping it within the specified width. This graphical representation is crucial for conveying information effectively in various domains, whether it's business reports, scientific publications, or social science research. By applying your statistical knowledge to data visualization tasks, you contribute to decision-making processes and problem-solving endeavors across different fields.
### 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}')
