<｜begin▁of▁sentence｜>### Instruction:
Given a graph which you can read from 'graph_data.gml', can you use the diversity function in igraph on a specified vertex to get its diversity score? You need to print the diversity score for the vertex.
### Response:
import igraph as ig

# Load a graph from a GML file
g = ig.read('graph_data.gml')

# Assume that we have vertex id 0 and we want to calculate its diversity
vertex_id = 0
vertex = g.vs[vertex_id]

# Calculate the diversity of the specified vertex
diversity_score = vertex.diversity()

# Print the diversity score
print(f'Vertex {vertex_id} Diversity Score: {diversity_score}')
