Parallel Coordinate Map

This is an example of a Parallel Coordinate Graph which is used to visualize high dimensional geometry and analyze data specifically multivariate.  It shows a set of points in a n dimensional space, with a backdrop, and the lines are typically vertical and equally spaced.  A point is represented then on a poly line like above and the position of the vertex on the i-th axis corresponds to the i-th coordinate of the point.
