<｜begin▁of▁sentence｜>### Instruction:
As an Electrical Technician, you may be tasked with installing and optimizing lighting systems in large office buildings. If you have a blueprint of the building's layout, how can you use specialized lighting design software to apply advanced optimization algorithms to ensure an efficient and visually pleasing layout of the lighting fixtures?
### Response:
from igraph import Graph

# Load your graph (here we assume it's a GML file, but it could be any supported format)
g = Graph.Read_GML('your-graph.gml')

# Apply the graphopt layout algorithm
layout = g.layout_graphopt()

# You might want to visualize the layout
plot(g, layout=layout)
