Due to the increasingly digital nature of library resources and collections, it is sometimes difficult envision a library’s unified holdings understand how they have changed over time. Conducting collection analysis applying data visualization techniques can be an excellent way get top-down view as whole. This article outlines author’s process for Weinberg Memorial Library’s entire catalog prin...

There is a rising trend of data analysis and visualization tasks being performed on a tablet device. Apps with interactive data visualization capabilities are available for a wide variety of domains. We investigate whether users grasp how to e↵ectively interpret and interact with visualizations. We conducted a detailed user evaluation to study the abilities of individuals with respect to analyz...

Abstract This paper proposes a visualization recommender system for tabular data given intents (e.g., “population trends in Italy” and “smartphone market share”). The proposed method predicts the most suitable type line, pie, or bar chart) visualized columns (columns used visualization) based on statistical features extracted from as well semantic derived intent. To predict appropriate type, we...

We introduce the notions of systems of equivalence relations, affine ordered sets and projective ordered sets to draw connections between many-valued contexts, geometry, and order-theory. This gives rise to applications in data analysis and data visualization.
