Node Graph Assistance

[thaliaspencer]

Hi,

I am a fairly new Grafana user but am learning a lot and am quite excited. I have been assigned to make a node graph replicate the assigned photo and feel I am having issues within the "edges" section, (because I can't see both parts connected) as well as the fine-tuning like colors, etc. Any help is appreciated.

**what I am seeking as the end result

**builder code so far

much appreciated :)
