Populating surface with "random" circles on U V grid

Hi All--

I'm trying to populate a surface with "random" circles.

I wish to to place an underlying UV grid on the surface where the circles will be populated from.

I want the circles to appear randomly placed (some are randomly culled or omitted) while still controlling the maximum distance one circle can be from one another (structural reason)

Here's what I have so far. I found this circle packing script on the forum and attempted to add a Divide Surface component but it doesn't look right.

Thanks!
