Visualizing this

How exactly should we visualize sigma and pi bonds in a molecule?

I base the sigma and pi bonds off of how many bonds are present:
1 bond= sigma
double bound= sigma + pi
triple bond= sigma +2 pi bond

We should visualize sigma bonds as the head-to-head overlap of two sp2 orbitals and pi bonds as the side-to-side overlap of two 2p orbitals.

It is also important to note that sigma bonds allow the atom to rotate while pi bonds do not.

I like to think of sigma bonds as a long cylinder and pi bonds as like a bubble encasing the sigma bond thats connected on either side.
___pi____
| ________ |
C |--sigma |C
|____pi____|


so for my attempt here, imagine that the dashed line and solid line above it comprise of a cylinder like shape which make up the sigma bond and the pi bond is almost like 2 cylinders on top and bottom of it but connected on each side.
