<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from graph_data.gml, can you use the personalized_pagerank method in igraph for a specific vertex (let's say the first vertex in the graph) to calculate the PageRank values with respect to that vertex and return the results for all nodes?
### Response:
import igraph as ig

# Read the graph
G = ig.read('graph_data.gml')

# Get vertex with id 0
v = G.vs[0]

# Calculate personalized PageRank for the selected vertex
pagerank_scores = v.personalized_pagerank()

# Print PageRank scores for all vertices
print(pagerank_scores)
