• tikz-qtree
  The LaTeX package provides a macro for drawing trees with TikZ using the easy syntax of Alexis Dimitriadis' Qtree. It improves on TikZ's standard tree-drawing facility by laying out tree nodes without collisions; it improves on Qtree (qtree) by adding lots of features from TikZ (for example, edge labels, arrows between nodes); and it improves on pst-qtree in being usable with pdfTeX and XeTeX.
