Definition
Multivariate visualization by scatterplots is the usage of diagrams to visualize sets of data that have more than three variables.
A scatterplot is a chart or mathematical diagram displaying a set of data as a collection of points using Cartesian coordinates, usually defined by horizontal and vertical axes. Each point on the chart represents two variables, x and y, calculated independently to form bivariate pairs (xi, yi). A functional relation between x and y is not necessary. The purpose of a scatterplot is to reveal (if existing) the relation between the displayed variables.
Introduction
Multivariate visualizations deal with the challenge of displaying sets of data with three or more variables: this peculiar feature poses two kinds of problems. First, most of the charts and diagrams usually adopted to visualize data cannot display more than three dimensions...
