# 3D visualizations

Since computer screens and paper are both two-dimensional objects, most plots are best suited to visualizing two variables at once. For the case of three continuous variables, you can draw a 3D scatter plot, but perspective problems usually make it difficult to interpret. There are some "flat" alternatives that provide easier interpretation, though they require a little thinking about to make.

`taiwan_real_estate`

is available; `magrittr`

, `plot3D`

and `ggplot2`

are loaded.
