Many thanks to Charlie Gunn for his mathematical suggestions and technical advice. Thanks also to Stuart Levy for his contributions to the Webviz and WebOOGL software and Daeron Meyer for his work on WebOOGL. I would like to acknowledge Ed H. Chi for his original program which constructed a Euclidean graphical representation of a piece of the Web as shown in Figure 2.
