Drawing Trees Nicely with TeX

SUMMARY We present a new solution to the tree drawing problem that integrates an excellent tree drawing algorithm into one of the best text processing systems available. More precisely, we present a T E X macro package called TreeT E X that produces drawings of trees from a purely logical description. Our approach has three advantages: labels for nodes can be handled in a reasonable way; porting TreeT E X to any site running T E X is a trivial operation; and modularity in the description of a tree and T E X's macro capabilities allow for libraries of subtrees and tree classes. In addition, TreeT E X has an option that produces drawings that make the structure of the trees more obvious to the human eye, even though they may not be as aesthetically pleasing.
