Python for Machine Learning - The Complete Beginners Course - 3D Visualization of the Predicted Values

The video tutorial explains how to predict the key mean on dataset X and create visualizations using Python's plotting library. It covers defining a figure, creating a 3D plot, and generating scatter plots for both the original and predicted data. The tutorial also demonstrates how to highlight cluster centers with star markers and sample from predicted values.

Explain the significance of the color and marker used in the scatter plot.

How are the predicted values sampled in the context of the data visualization?
