Grasshopper Spreading Grid

Hi everyone,
start by saying that I do not use grasshopper (I only read of the basic concepts), however I need to exploit it in order to realize a concept for an architecture project.
I downloaded an algorithm that responds "ALMOST" to my needs.
What I'm trying to achieve is an orthogonal grid within which are inserted points defining the centers of some circles. These circumferences then cause the tensions that deform the grid.
The only problem is that the algorithm that I downloaded defines the same radius for each point, or rather defines a random radius.
What I would do is to define a different radius I specify for each point.
Can any of you help me?
I attach images and grasshopper and rhino files

Thanks
