<｜begin▁of▁sentence｜>### Instruction:
As a User Experience Researcher, I help organizations gather feedback and conduct studies to enhance the user experiences of their products or services. I'm currently tasked with analyzing a graph representation of user interactions in a productivity app. To ensure a comprehensive understanding, I need to identify all the attribute names associated with the vertices of the graph, which I can access from the graph_data.gml file. This will enable me to delve deeper into the user behavior and preferences within the app.
### Response:
from igraph import Graph

# Load a graph from a file (assuming GML format for the example)
g = Graph.Read_GML('graph_data.gml')

# Get the attribute names of the graph's vertices
vertex_attribute_names = g.vs.attribute_names()

# Print the attribute names
print(vertex_attribute_names)
