Too bad we don't have a mark "Enjoyed-by:" ;).
Yes, it does fit 80 characters limit. It was created manually. I stumbled
upon https://pythonhosted.org/asciitree/#ascii-trees the other day, but
never used it, you may find it useful.
By the way, there is a serious science on creating such trees in the most
compact or balanced way. See, for example, Reingold-Tilford algorithm
("Tidier Drawings of Trees", 1981).
