Andrews Curves

Andrews curves are a method for visualizing multidimensional data by mapping each observation onto a function. It has been shown the Andrews curves are able to preserve means, distance (up to a constant) and variances. Which means that Andrews curves that are represented by functions close together suggest that the corresponding data points will also be close together.
