actually is there a graphic way for understanding why we can get a perspective by just dividing the z component... I am not able to find a mathematical meaning of dividing z component.

I think if z is big, the object is further away so when dividing by z, x and y will be smaller, so the object will be smaller when further away, and vice versa.

For the reason to divide z, you can take a look at this slide: http://15462.courses.cs.cmu.edu/spring2020/lecture/intro/slide_038 for reference.
