[TUTORIAL] Summoning particles in a circle shape (with template procedure)

For this tutorial, I'll provide a procedure template that you can use to summon a ring of particles. You can download the template here.

Procedure

This procedure will require the world, x, y, z dependencies.
Before importing the procedure, you need to add these local variables: "loop", "particleAmount", "xRadius" and "zRadius". All of them are number variables.
After importing the procedure, it should look like this:

You can change some parameters to customize your ring:

The red one is the particle amount: make sure it's greater than 0
The yellow ones are the radii of the ring on the X and on the Z axes. If they're the same value, the ring will be a circle. Otherwise, the ring will be an ellipse
The green ones are the center of the ring.

Examples

This is what the default ring looks like:

Another ring. particleAmount is set to 16, xRadius and zRadius are set to 2:

Yet another ring. particleAmount is set to 14, xRadius is set to 3, zRadius is set to 1:
