TLDR
A generalization of the scatterplot matrix is developed based on the recognition that most datasets include both categorical and quantitative information and may help to reveal structure in multivariate data that otherwise might go unnoticed in the process of exploratory data analysis.Abstract:
This article develops a generalization of the scatterplot matrix based on the recognition that most datasets include both categorical and quantitative information. Traditional grids of scatterplots...read more
