Thanks, but Jürgen's example was sufficient.

The example I attached was extremely simplified compared to what I actually
need to make--as I said in my original post, there are various typographic
bells and whistles that need to go into the node labels, including IPA,
small caps, Greek letter subscripts, and other things. So I am going to
have to fine-tune node positioning.

I prefer to have everything in one document whenever possible, for visual
consistency and for passing the paper to the's journal proof people. The
disadvantage of the method you suggested is that one has to tweak the image
size so that the fonts look like they came from the same universe. And then
if anything changes in the diagram, you have to redo it in multiple places.

Steve, both linguists and mathematicians use LaTeX for lattices, trees, and
various other graphical diagrams. The reason to do so is the one I alluded
to above: they mix text with graphics, and often they have to include text
with math typesetting. We've been doing this for decades.
