3D graphic effects with animation nodes

I’m a novice in using Blender and I have to create with the animation node’s addon a 3D graphic effect of “connecting dots”. In detail: a certain amount of spot spreaded randomly in a dark space become illuminated without an order. In a second time all those spot light begin to link together randomly with emitting segment that starts from the spots themselves. I need to develop the correct node map. Thanks to everyone who would like to help me.
