How to do circle packing within a boundary with various attraction points. (2D)

Hi all,

I'm new to grasshopper and are trying to do circle packing within a boundary where the radius of the circles will vary based to it's distance from various attraction points, does anyone know a simple way to do this? Or is Voronoi easier?

In the end I would like it to resemble the formation of these plant cells in the images attached.

Thank you in advance for your help!
