Zenplots, like pairs plots (scatterplot matrices), lay out a large number of one- and two-dimensional plots in an organized way.
Unlike pairs plots, zenplots can lay out a much larger number of plots by pursuing a zigzagging layout (following a zenpath) of alternating one- and two-dimensional plots.
The plots can be created by R's base graphics package, by the grid graphics package, or even made interactive (brushing, etc.) by using using the loon package.
