Visualizing three numeric variables

There are also some "flat" alternatives to 3D plots that provide easier interpretation, though they require a little thinking about to make. A good approach is plotting the two numeric explanatory variables on the x- and y-axis of a scatter plot, and coloring the points according to the response variable.

taiwan_real_estate is available.
