selforientation of circles to a sphere

Hello!

I´m really new in grasshopper and i have problem. The Idea was to create a sphere by selforientating cricles with different radians. the circles have to hold a minimum distance between. so that, if the distance is 2 the sphere getting bigger, is the distance 1 the sphere getting smaller. its an idea between voronoi and just orientation on surface. know i got that the circles orient themselves, but they are overlapping and the distance between them is different. there is the rhino and gh data attached with a pic of the problem. i hope someone can help me, please! its for my thesis and the deadline on friday.
