Help Snapmap style code in unity?

I recently tried out doom's snapmap and enjoyed how quick and simple the visual, connect the dots style scripting was, and was wondering if anyone has heard of any addons or prefabs for Unity that work similar. I mean connecting physical bubble style scripting, similar to visual scripting but more modular and simple for anyone to use. If something like this can be made, I feel like it would be easier for beginners to make simple games or to learn Unity. While I know it doesn't beat good coding, snapmap features and code together could make some very interesting style games.
Here are examples of snapmap.
