Down. As @Shamim mentioned, this aligns with the “depth-first” terminology.
In computer science, trees are usually drawn with the root node on top, and the leaves at the bottom (i.e. upside down). It makes little sense but I presume it’s easier than correctly estimating how much space you’ll need to draw it “the right way up”.
There’s a similar question on Quora: Why are trees in computer science generally drawn upside-down from how trees are in real life?
And the Wikipedia article seems to agree.
