1. A method for visually representing the interactions of a plurality of input variables and at least one output variable, the method comprising the steps of: generating a visualization field on a display device, said visualization field including a peripheral line extending around said visualization field; generating on said display device a plurality of input variable indicators representative of at least one of the plurality of input variables; positioning each of said input variable indicators approximately on the peripheral line of said visualization field; generating on said display device at least one interaction indicator, said interaction indicator being an indicator of a combination of at least one input variable, wherein each interaction indicator includes at least one association indicator which graphically identifies, within the visualization field, at least one of the input variables associated with said interaction indicator; positioning each of said interaction indicators within the periphery of said visualization field; and adjusting the appearance of said at least one interaction indicator on said display device to reflect at least one value of said at least one output variable.
