Abstract
This report describes the application of functional programming techniques to a problem previously studied by imperative programmers, that of drawing general trees automatically. We first consider the nature of the problem and the ideas behind its solution, independent of programming language implementation. The functional language implementation is described in a bottom up style starting with very general functions over trees and then narrowing in on the particular tree layout algorithm. Its correctness is considered informally. Finally we discuss the implementation’s computational complexity and possible improvements.
