How to make lines from the add sop follow the normals?

[Jag80]

I've been working on some lightning tutorials and they use a scatter node to scatter points on the surface and then use a add sop to create some lines. I have a circular radius that I would like the lightning to shoot from the center outward, but I having trouble with it. I've made the normals shoot off in an outward direction on all sides, but the way the add sop puts down the lines is random. Is there a way to make it more uniform so they are going the direction of the normals?

Add sop creates a polyline between the points in order, the scatter sop randomizes point order by default hence the messy appearance.

You could do branching lighting with some vex growth, an l-system or shortestpath sop. One approach might be:
