Code4Lib Journal > On Dentographs, A New Method of Visualizing Library Collections

The Code4Lib Journal

A dentograph is a visualization of a library’s collection built on the idea that a classification scheme is a mathematical function mapping one set of things (books or the universe of knowledge) onto another (a set of numbers and letters). Dentographs can visualize aspects of just one collection or can be used to compare two or more collections. This article describes how to build them, with examples and code using Ruby and R, and discusses some problems and future directions.
