Data Science and Machine Learning (Theory and Projects) A to Z - Plotly for 3D Interactive Plotting: Plotly 3D Interacti

The video tutorial guides students through creating a 3D surface plot similar to one from a previous lecture. It covers setting up X, Y, and Z values using meshgrid and linspace, configuring the plot with a specific color scale, and finalizing the interactive display. The tutorial emphasizes the simplicity of the process and encourages students to apply these techniques independently.
