<｜begin▁of▁sentence｜>### Instruction:
As a literary agent representing authors and writers, let's delve into a scenario where you're collaborating with a talented illustrator to create an engaging book cover for your client's latest novel. The illustrator needs to incorporate a snippet of text, "Some text goes here," onto the cover in a visually appealing manner.

To ensure the text fits seamlessly within the design, you need to calculate its layout, starting at specific coordinates (50, 50) on the canvas. The maximum width for the text is constrained to 200 pixels, allowing it to wrap naturally if needed.

Once you've determined the layout details, you'll provide this information to the illustrator so they can manually draw the text onto the canvas using the Cairo graphics library. This library offers various methods and functions for precise drawing, enabling the illustrator to accurately position and render the text according to the calculated layout.
### Response:
import igraph as ig
import cairo

# Create a graph
graph = ig.Graph.Tree(3, 2)

# Set up a Cairo surface to draw on
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, 300, 300)
context = cairo.Context(surface)

# Create a CairoTextDrawer
text_drawer = ig.drawing.text.CairoTextDrawer(context, halign=ig.drawing.text.TextAlignment.left)

# Set some text
text_drawer.set_font_face('Arial')
text_drawer.set_font_size(12)

# Calculate the text layout
layouts = text_drawer.get_text_layout('Some text goes here', x=50, y=50, width=200, wrap=True)

# Now we can use the layout information to draw the text manually
for x, y, line in layouts:
    context.move_to(x, y)
    context.show_text(line)

# Save the result to a file
surface.write_to_png('text_layout.png')
