    Abstract

    The amount of literature within a research domain is ever growing, thus making it difficult to stay on top of everything. Getting a grasp on the important topics of and areas within a domain or even knowing where to start is often tough and tedious. This paper therefore presents a visualization, that is a cluster spiral, that offers a fast but plain and simple way of exploring the content of large text collections.
