<｜begin▁of▁sentence｜>### Instruction:
Given a graph (e.g., the famous Zachary's karate club graph), can you compute the cocitation scores for all vertices within that graph?
### Response:
from igraph import Graph
import numpy as np

# Load a graph (this will depend on your data source)
g = Graph.Famous('Zachary')

# Compute cocitation scores for all vertices
scores = g.cocitation(vertices=None)

# Convert scores to a numpy array for better usability
scores_array = np.array(scores.data)

# Print the cocitation score matrix
print(scores_array)
