Hi and thanks for you work. This is really useful for teaching my students.
Could you add an option to get a different output graph : the upper half of the tree only with the parameters and the lower half with an symetric, inverted tree, with all the values return, just like this :

Thanks again for this great library.

Thanks for the feedback. The return values are already on the existing graph nodes. Maybe i'm not seeing it, can you share how is the inverted tree representation more useful?
