RadViz: Improvements on Radial-Based Visualizations++

Lucas de Carvalho de Carvalho Pagliosa, Alexandru C. Telea
2019 Informatics  
To address these limitations, we propose RadViz++, a set of techniques for interactive exploration of high-dimensional data using a RadViz-type metaphor.  ...  RadViz is one of the few methods in Visual Analytics able to project high-dimensional data and explain formed structures in terms of data variables.  ...  The funders had no role in the design of the study; in the collection, analyses, or interpretation of data; in the writing of the manuscript, or in the decision to publish the results.  ...
