Why is mix xref graph with a source and a sink giving me all these useless branches?

There happens to be a single path from my source to my sink, yet I get a 800+ line output.
There is only a single line where my sink appears.

Maybe this is due to some cycles? Even then most leaves don’t seem pertinent…

$ mix xref graph  --source lib/bobby/underwriting/rule/life/xyz_test.ex --sink lib/bobby_web/views/documents/life_view.ex

Is there a way to get the output I want:
