<｜begin▁of▁sentence｜>### Instruction:
As a lighting designer working on a new architectural project, I would like to use the layout_mds function in igraph to arrange the lighting fixtures in a 2D space using multidimensional scaling, in order to optimize the lighting design and obtain their precise coordinates. The data for the project can be accessed from the file 'graph_data.gml'.
### Response:
from igraph import Graph
import igraph as ig

g = ig.read('graph_data.gml')

# Use multidimensional scaling to layout the graph
layout = g.layout_mds()

# Convert layout to list of tuples
coordinates = [(point[0], point[1]) for point in layout]

# Print the coordinates for each vertex
for idx, coord in enumerate(coordinates):
    print(f'Vertex {idx}: {coord}')
