Z-Plotter version 2.0 by Sean Barnes is a three-dimensional plotting
program that allows you to choose an equation and plug in various
ranges for the X, Y, and Z axis. The maximum and minimum ranges for
the X, Y, and Z axis are used as a virtual "telescope", allowing for
a local sighting or a worldly view of a specified graph. A graph can
be plotted in various resolutions by changing its resolution factor.
