Create a cheat sheet (A4 overview) with the three elemental paths within a DAG (pipe, fork, collider), listing their name, the minimal DAG (where X does not affect Y directly), the association between X and Y when stratifying by Z or not, and a visualization of the statistical association (with a binary $Z={0, 1}$). The visualization shall plot X and Y on the two axes, Z via differing colors, and include regression lines for both strata of Z as well as the total sample.
