I want to visualize everything in Mathematics.Is there a way to visualize the theorem I stated above?Can it be represented graphically?I want to be very analytical in this topic.So please can anyone suggest a good visualization or a textbook that discusses such topics? I want a visualization for this particular theorem.

Here's a geometric description of finite cyclic groups:

A finite group is cyclic if and only if it is isomorphic to a finite group of rotations of the circle $S^1$.

For example, the cyclic group of order $6$ is isomorphic to the group of rotations of $S^1$ through the $6$ angles $\frac{2\pi}{i}$, $i=0,1,2,3,4,5$.

Once you believe that this description of finite cyclic groups is true, or once you go to the trouble of proving that it is true, then here's a very simple "visual" proof that every subgroup of a finite cyclic group is cyclic: every subgroup of a group of rotations of $S^1$ is also a group of rotations of $S^1$.
