How to use N output from Topologizer in GH?

I’d be very appreciative if someone could give me an example of how I could use the N output of Topologizer to create new geometry if points are connected. So for example, use the info from the N output to check if 1 is connected to 4, and if it is then create a circle of Xm radius Ym away at Z degrees from point 1. Thank you (11.7 KB)
