This is extremely cool. Picked it up and made this DAG in like 15 minutes. Obviously pros/cons versus other DAG tools (e.g. low/no code cstructure and R's ggdag, both of which offer d-separation details and more) but if you have rigid aesthetic requirements this is a great tool to have in your kit

{truffle} is an R package for teaching users to process data. Semi-realistic psychological datasets with predetermined effects (via `truffles_` functions) are then hidden in common data processing headaches (via `dirt_` functions) for students to clean and analyze. mmmdata.io/posts/2025/0...
