Abstract This paper is interested to show a new data visualization tool to study economics. The new data visualization tool is called “Infinity Cartesian Space (I-Cartesian Space)”. The I- Cartesian Space can show from a different visual perspective an economic phenomenon. The study case to apply the I-Cartesian Space is the study of oil prices from 1960 to 2010. In this study case is possible to observe the oil prices behavior change dramatically after 1970’s but especially from 1990’s until 2010. The vulnerability of oil prices can be observed clearly on the I-Cartesian Space. The vulnerability of prices is based on the changes under the same price range into the same Cartesian Space. The I-Cartesian Space shows two ranges of prices, there are stable price level and price instability level. Keywords: Econographication, economic mathematics, economic methodology. 2. Infinity Dimensional Cartesian Space (I-Cartesian Space) Theoretical Framework The Infinity Cartesian Space (I-Cartesian Space) will be an alternative Cartesian Space to visualize different type of graphs from different perspective. The I-Cartesian Space is formed by n independent variables (x 1 , x 2 , x 3 …x n ; n =1…+∞) and one dependent variable that is “y”. But “y” can have positive and negative values. The new modality of “y” is that this variable can be located in different positions into the circle parametric of the infinity Cartesian Space. The circle parametric is formed by join all x i (x 1 , x 2 , x 3 …x n ) until to create a cylinder. We assume that “y” has high mobility into the circle parametric. The position of “y” in the circle parametric is depends on the analysis we are interested to develop or demonstrate. We can observe that the final graph is a cylinder with different levels of dimension in the time and space. The graphs in the I-Cartesian Space can generate • The author of this paper is lecturer in the International Institute of Public Policy and Management (INPUMA) at University of Malaya, Kuala Lumpur, Malaysia.
