This is a starplot. Each of the axis represents a something to measure about the subject. In this car example, the axis represent price, mpg rating, repair rates, headroom, rear seat room, trunk space, weight, and length. By having multiple axis, the plot is able to communicate a lot of information about the car, and the user is able to compare a lot of features among many cars easily. For example, it seems that many of the cars sacrifice great mileage to have other features like headroom, rear seat room, trunk space, weight and length.
