Path Algorithm

Greetings!

      I am looking for help in a school project, the idea was to create a grid of circles which would serve as paths. Through these paths shapes can be formed dynamically through a loop using rules to assure that these are valid. I have the paths needed but do not know how to tell rhino to go across one arc and jump to the next circle and so forth to create kinda like atom shapes. I will attach the definition and an example of what kind of shape i was looking for in a model from Rhino.
