Hi,
I think this is a simple question; not sure. Any thoughts or ideas would be
greatly appreciated:
Instead of dot density or ranges, which seem to have a maximum of 16 levels,
it possible to do a map with a (relatively) continuous gray scale?
According to Ed Tuft's _Visual Display of Quantitative Information_, a
continuous gray scale is one of the best ways to represent a continuous
variable.
