Hello,

Take a look here at the Cartesian Coordinates:

> **[Spherical coordinate system](https://en.wikipedia.org/wiki/Spherical_coordinate_system)**
>
> In mathematics, a spherical coordinate system is a coordinate system for three-dimensional space where the position of a point is specified by three numbers: the radial distance of that point from a fixed origin, its polar angle measured from a fixed zenith direction, and the azimuthal angle of its orthogonal projection on a reference plane that passes through the origin and is orthogonal to the zenith, measured from a fixed reference direction on that plane. It can be seen as the three-dimensi...

I used my original example for the random points, a translate, a rotate for _phi_ and a rotate for _theta_ and then drew a circle():

This approach was fresh in my head from a recent project.
