How can I add annotations to a 3D plot in Matplotlib?

You can use the text method from the Axes3D class to add annotations. Here's a simple example.

Can you show me a code snippet for that?

Sure! Here's a basic example:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Sample data
x = [1, 2, 3]
y = [4, 5, 6]
z = [7, 8, 9]

ax.scatter(x, y, z)

# Adding annotations
for i in range(len(x)):
    ax.text(x[i], y[i], z[i], f'Point {i}', size=20, zorder=1)

plt.show()

What if I want to customize the annotation text style?

You can customize the text style by using parameters like size, color, and fontweight in the text method. For example:

ax.text(x[i], y[i], z[i], f'Point {i}', size=15, color='red', fontweight='bold')
