Radviz plots

Radviz plots allow for the exploration of multi-task classification problems. It displays data of three or more variables in a two-dimensional projection. This plot is like a circle with data points inside it. The variables are present around the perimeter of the circle.

The position of each point is determined by the values of all the variable values that make it. An imaginary circle is created and the variables are placed on this circle. The points are placed within the perimeter of the circle. The exact position of the point is determined by the position where the force that's exerted on it by each variable sums to zero. The force that's applied by each variable can be thought of as a spring force and is governed by Hook's ...
