<｜begin▁of▁sentence｜>### Instruction:
As a child birth educator, you might encounter a situation where you need to prepare educational materials for expectant parents, such as prenatal graphs and charts, using igraph. In this scenario, you may need to ensure that when writing the information to a file using GML format, decimal points are used instead of commas, regardless of the current system's locale settings. This is important to maintain consistency and accuracy in the representation of data for parents from diverse backgrounds.
### Response:
from igraph import Graph
import igraph as ig

# Create a simple graph
g = Graph.Erdos_Renyi(n=10, m=15)

file_path = 'graph_output.gml'

# Use safe_locale to ensure decimal points are used in file output
with ig.utils.safe_locale():
    g.write_gml(file_path)
