scale_adjusted() is a convenience function that implements ways of visualizing adjustment for a variable. By convention, a square shape is used to indicate adjustment and a circle when not adjusted. Arrows out of adjusted variables are often eliminated or de-emphasized, and scale_adjusted() uses a lower alpha for these arrows. When adjusting a collider, a dashed line is sometimes used to demarcate opened pathways, and scale_adjusted() does this whenever geom_dag_collider_edges() is used. scale_dag() is deprecated in favor of scale_adjusted().
