  Interactive visualizations for exploring and retrieval have not yet become an
integral part of digital libraries and information retrieval systems. We have
integrated a set of interactive graphics in a real world social science digital
library. These visualizations support the exploration of search queries,
results and authors, can filter search results, show trends in the database and
can support the creation of new search queries. The use of weighted brushing
supports the identification of related metadata for search facets. We discuss
some use cases of the combination of IR systems and interactive graphics. In a
user study we verify that users can gain insights from statistical graphics
intuitively and can adopt interaction techniques.
