<｜begin▁of▁sentence｜>### Instruction:
As a photographer, imagine you are using specialized software to enhance and manipulate images. You are asked to utilize a specific tool within the software to calculate the Laplacian matrix of a visual graph representing the interconnectedness of various elements within an image. Can you explain how to use the Graph.Graph.laplacian function in the software to achieve this and display the resulting matrix?
### Response:
from igraph import Graph

# Define the edges of the graph or load a pre-existing graph
g = Graph(edges=[(0, 1), (0, 2), (1, 2), (2, 3)])

# Calculate the Laplacian matrix
laplacian_matrix = g.laplacian()

# Print the Laplacian matrix
print(laplacian_matrix)
