This is a scientific illustration I made while working as a research assistant at the signal processing laboratory of the Geneva Engineering School .
It is meant to help students understand the relationships between the Z transform and the Fourier transform.
Basically, the Fourier domain (shown here in red) is a subset of the Z domain (shown here as a beige surface).

If I understand your video, I guess a more correct explanation would be:
- the xy-axes are the domain of the Z-transform
- the gray surface is the Z-transform of some function
- the red line is the Fourier transform of the same function.
- the green cylinder shows that the domain of the Fourier transform is the unit circle on the complex plane
...please correct me if I am wrong.

@nippie96 That's exactly right. Thanks.
