Point Configuration: Radius

### Documentation Is:

- [ ] Missing or needed?
- [X] Confusing
- [ ] Not sure?

### Please Explain in Detail...

https://www.chartjs.org/docs/latest/configuration/elements.html#point-configuration

In the Radius section of the Points configuration, it specifies that the radius is of type Number, but it actually also accepts an array of numbers.

I have spent a day and a half looking for an alternative solution to paint different radius values. If I had known that something like this was possible:

radius: [0, 0, 0, 0, 0, 6, 6, 6, 6, 0, 0, 0]

And not just like this:

radius: 6

Thanks
