Plotting - Non-linearity and Heteroscedasticity in Regression Models

[BHM]

Hi, 

Referring to the attached plot - how can such models be plotted in ggplot.  

Sample data could be any regression model, say the following: 

attach(cars)
r.mod = lm(dist~speed,data=cars)

Regards /

ggplot2 does not do 3D plotting. Lattice might be able to do something
like this, though, and the latticeExtra packages has a ggplot2like
theme function to make it resemble a ggplot2 graph.
