I think everyone is over thinking this - you just need:

Sphere SOP > Polywire SOP

Adjust Polywire settings to taste.

PoppyPLOuf - it would have probably been better to start a new thread : ) Tagging on to the end of the 2019 one is likely to cause confusion. Particularly as your question is not the same as the original.

Anyway: if you want your scattered points to be at different radii relative to the centre, do this:

Add a 'Attribute Adjust Vector' SOP with the following settings:
Attribute name : P
Adjust value > Adjustment for: Length only
Operation to: Subtract
Adjust with: Random
Min / max as you prefer (eg: min 0.5 / max 1.0)

This will move the points randomly inwards towards the centre of your sphere.
You can then use those points to do a copy to points operation etc.

NOTE: All this is assuming your sphere is located at object centre, ie: 0,0,0

NOW : )
