Parallel Coordinate Graph

Parallel Coordinate Graph- A useful geovisualization tool for plotting and expressing relationships among many variables for a given subject of interest. Each variable is graphed on a vertical axis, and a data element is plotted a a connected set of points, one on each axis. This is a parallel coordinate graph describing car models released from 1970 to 1982, and contains their mileage (MPG), number of cylinders, horsepower, weight, and year they were introduced. It can be seen that generally, and inverse relationship exists between miles per gallon and number of cylinders. The more cylinders a car sports, the lower the mpg. A weaker relationship exists between number of cylinders and horsepower, though on the whole a car with fewer cylinders will fall on the lower end of the horsepower spectrum, and vise versa (http://www.fas.org/irp/imint/docs/rst/Sect16/Sect16_3.html).
