Perform MDS on the distance matrix.

thanks , it works

import numpy as np
import matplotlib.pyplot as plt
from sklearn.manifold import MDS

def main():
    try:
        distance_matrix = np.load('distance_matrix.npy')
    except Exception as e:
        print(f"Error loading distance matrix: {e}")
        return

    print(f"Distance matrix shape: {distance_matrix.shape}")

    try:
        mds = MDS(n_components=2, dissimilarity='precomputed', random_state=42)
        points = mds.fit_transform(distance_matrix)
    except Exception as e:
        print(f"Error performing MDS: {e}")
        return

    plt.figure(figsize=(10, 8))
    plt.scatter(points[:, 0], points[:, 1])
    plt.title('MDS Projection of Distance Matrix')
    plt.xlabel('MDS Dimension 1')
    plt.ylabel('MDS Dimension 2')
   
    for i, point in enumerate(points):
        plt.annotate(str(i), (point[0], point[1]))

    plt.show()

if __name__ == "__main__":
    main()

after i run the code code export the img , but img is not clear to read how fix it

You can change font size here:

plt.annotate(str(i), (point[0], point[1]), fontsize=6)
