Populate 2D with different density based on attractor

Hello everyone!

i might have a simple question but i cannot find a way to solve it.

I have already searched the forum for solutions but i haven't quite find the answer.

As the title says, i have a surface with a population of points on it, and i would like to have those points arranged at different density based on attractor points (and later line attractors). i attach a simple hand-made screen of what i mean.

My ultimate aim,btw, is to have a double curved surface with a voronoi pattern on it, with different density of the cells (not the cell size, as i found in other posts), that's why i first need to create the voronoi base points based on attractors.

thanks
