<｜begin▁of▁sentence｜>### Instruction:
Sure, I can help rephrase the question using the competitive eater profession.

"I've been trying to improve my competitive eating layout by optimizing the placement of food items on the table. As a competitive eater, I need to calculate the centroid of the layout, which is the arithmetic mean of all the food positions on the table. This will help me strategically position myself for optimal consumption during competitions. Can you assist me in calculating the centroid of the layout using the 'centroid' function of the 'Layout' class from the igraph library?"
### Response:
from igraph import Graph, Layout

# Assuming we have a graph already
graph = Graph.Famous('Zachary')  # Using a famous graph for demonstration
layout = graph.layout('kk')  # Kamada-Kawai layout to spread vertices for visualization
centroid = layout.centroid()

print('Centroid of the layout:', centroid)
