Grasshopper

algorithmic modeling for Rhino

Still new to Grasshopper and using fields & attractors.  I'm trying to use several point attractors to pull other random points towards the attractors based strength by distance (simple enough, right?).  I understand (kind of) how the point attractors can be used to modify the scale of circles, for example (like most basic tutorials show).  However, I can't seem to get the random points to move towards the attractors properly.  I'm sure it has to do with vectors and adding vectors, but I don't really understand how they work.

Thanks,

dude...that's awesome.  I will definitely try this out, thanks.

One more thing, I don't understand what the "Data with 3 Branches" or "Data with 1 Branch" are or where to find them.  

I am attempting to produce these cluster so I can make dense regions of vertical members with paths winding through them.  Is this something that can be achieved with this definition?

Is it possible to make it so ALL the points repell/attract. The minimum range still leaves one point that doesn't move. I need ALL of them to move
