Exercise: Subplots

Challenge

Write Python code to make four subplots on a $3\times3$ matrix inside a figure. The details of all four figures are as follows:

• Plot 1: 3D surface plot on rows 1 and 2 and columns 1 and 2

• Plot 2: Polar plot on row 1 and column 3

• Plot 3: Horizontal bar plot on row 2 and column 3

• Plot 4: 2D scatter plot on row 3 and columns 1, 2, and 3

The visual representation of the final figure is shown below.
