Grid with Random Proximity Connections

Hello

I am trying to create a definition which takes a number of random points from a selection of points, then finds their 2 closest points, (could be more), from those randomly selected, and connects them with a line.

I have managed to do that but it ends up with loose ends.

I wonder whether it is better to find the closest points from those further down the list each time, (those which have already been given x number of buddies to join with). Therefore, I might get an expanding net rather then disconnected bits.

I am referencing this project, (link below), and have attached an image of the aim, the rhino file and gh.

Any help would be greatly appreciated, (I am a novice at GH but trying to get better)

Thanks

Amanda
