I need to draw a tree, and constantly using dotty and including the PNGs is starting to be a pain. Is there a way to get LaTeX to draw it's own trees that doesn't involve learning an entirely new language like TikZ?
While I'd normally second Will Robertson's comment, since TikZ is fantastic and worth learning, I think TikZ's overkill for this situation. I personally find its tree specification syntax bulkier than necessary. My preferred tool for the job is the qtree package (which is on CTAN, too, and is apparently included in both TeX Live and MikTeX). The package is really simple to use. Consider the following TeX:
This produces the following tree:
That's all it takes! And what's great about it is that the TeX description reads like the tree. I can glance at the TeX, and I instantly know what the created tree is going to look like. The basic syntax is simply
In general, you can provide node names at the beginning (
Now, qtree as-is has one downside, which is that it is designed for simple trees. It does offer limited support for changing inter-node spacing, framing parts of trees, and things like that, but it's not capable of doing anything incredibly fancy. But luckily, if you want that, you can still get it: enter tikz-qtree. This package allows you to leverage the full power of TikZ to draw your trees. The two obvious features are: (a) instead of text, the labels in a tree can be arbitrary
Maybe you don't need this power now, but the take-home message is that using qtree won't lock you in to the simple trees. If you decide that you want the more powerful trees, all you need to do is change one import; everything will keep working the way it did, but you get more power, too. I'm not sure if tikz-qtree this actually uses qtree under the hood or not, but either way, all the syntax for qtree still works, and the output is identical, at least as far as I can tell.
(PS: Linguists, please excuse/correct any errors in the above tree; it's been a year or two since my syntax course.)
For simple, non "graphical" tree you can use the
