Applet of Duality Transformation
An implementation of duality transformation. In a Cartesian plane, a point can be identified by two parameters, such as xcoordinates
and y-coordinates, and also a non-vertical line can be presented by
two parameters also, such as slope and y-intercept. The concept of duality is a
powerful tool for the description, analysis, and construction of algorithms
