MATA is an interactive data visualization artwork. The work invites the visitor to synchronize his breathing with each cycle of the fractals' animation. The speed of each cycle reflects INPE's data on deforestation in the Amazon, quantifications resulting from analyses of satellite images. The work uses the mathematical patterns present in the fractals that simultaneously refer to trees and lungs. The artistic visualization of data proposes a means of raising awareness through an interactive proposal in a video generated from the data. The work is in process of creation, being programmed in Processing.
