<｜begin▁of▁sentence｜>### Instruction:
As a Human Resources Manager responsible for overseeing all human resources activities within the company, I have been tasked with coordinating recruitment, training, compensation, benefits, and employee relations to align with our organizational goals and objectives. In this context, utilizing the networkx library in Python, I am looking to analyze a graph structure provided in the 'graph_data.gml' file using the "get_all_simple_paths" function to identify and examine all possible simple paths originating from node 0, without imposing any restrictions on path length. This analysis is crucial for understanding the connectivity and traversal possibilities within our network, enabling us to make informed decisions and optimize our resources effectively.
### Response:
from igraph import Graph

# Read the graph
graph = Graph.Read_GML('graph_data.gml')

# Source vertex
source_vertex = 0

# Calculate all simple paths from the source vertex to all other nodes
paths = graph.get_all_simple_paths(v=source_vertex, cutoff=-1, mode='OUT')

# Print paths
for path in paths:
    print(path)
