Journal ArticleDOI
UpSetR: an R package for the visualization of intersecting sets and their properties
TL;DR: UpSetR is an open source R package that employs a scalable matrix‐based visualization to show intersections of sets, their size, and other properties, and is released under the MIT License.
Journal ArticleDOI
UpSet: Visualization of Intersecting Sets.
TL;DR: This paper introduces UpSet, a novel visualization technique for the quantitative analysis of sets, their intersections, and aggregates of intersections, focused on creating task-driven aggregates, communicating the size and properties of aggregates and intersection, and a duality between the visualization of the elements in a dataset and their set membership.
Journal ArticleDOI
LineUp: Visual Analysis of Multi-Attribute Rankings
TL;DR: This paper proposes LineUp - a novel and scalable visualization technique that uses bar charts that enables users to interactively combine attributes and flexibly refine parameters to explore the effect of changes in the attribute combination.
Journal ArticleDOI
Comparative Analysis of Multidimensional, Quantitative Data
TL;DR: Matchmaker, a visualization technique that allows researchers to arbitrarily arrange and compare multiple groups of dimensions at the same time, is developed, and biologists use it to investigate why certain strains of mice develop liver disease while others remain healthy.
Journal ArticleDOI
The State of the Art in Visualizing Multivariate Networks
TL;DR: This state‐of‐the‐art report analyzes current practices and classify techniques along four axes: layouts, view operations, layout operations, and data operations and gives recommendations for which technique to use in which scenario.
