<｜begin▁of▁sentence｜>### Instruction:
As a network analyst at a transportation research firm, you've been asked to analyze the shortest routes within a transportation network graph that represents a city's road network, which is stored in a file called graph_data.gml. Your task is to calculate the shortest paths from a specific starting location (node with an ID of 0) to all other nodes in the network to better understand the most efficient travel routes and potential congestion points. You can accomplish this using the networkx library in Python, specifically utilizing the shortest_path() method to calculate the shortest paths within the graph.
### Response:
from igraph import Graph

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

# Calculate shortest paths from node 0 to all other nodes
shortest_paths = graph.get_shortest_paths(0)

# Print the shortest paths
for path in shortest_paths:
    print(path)
