concept 3d scatter plot in category R

This is an excerpt from Manning's book R in Action, Second Edition: Data analysis and graphics with R.
As you’ve seen in previous chapters, scatter plots describe the relationship between two continuous variables. In this section, we’ll start with a depiction of a single bivariate relationship (x versus y). We’ll then explore ways to enhance this plot by superimposing additional information. Next, you’ll learn how to combine several scatter plots into a scatter-plot matrix so that you can view many bivariate relationships at once. We’ll also review the special case where many data points overlap, limiting your ability to picture the data, and we’ll discuss a number of ways around this difficulty. Finally, we’ll extend the two-dimensional graph to three dimensions, with the addition of a third continuous variable. This will include 3D scatter plots and bubble plots. Each can help you understand the multivariate relationship among three variables at once.
