Matplotlib 3D surface plot

This surface plot shows the functional relationship between the specified dependent variable (Y) and two independent variables (X and Z). This graph is an accompanying graph of the contour plot. The surface plot is similar to the wireframe plot, but each face of the wireframe is a filled polygon. This can help perceive the topology of the visualized surface. The plot_surface() function takes x, y, and z as parameters.
