Plot tree families similar to illustrations in paper #51
Description
Would be nice both from an illustrative point of view to explain the method, and to get an idea of the data partitioning in low dimensional cases where there's not too much going on.
I think the $forest object should contain all the info needed for that but I don't know how to put it in a useful structure yet, and how to visualize it then.
Ideally something that could support interactivity, but a png would suffice I guess.
