Adapted Dorling cartogram on wage inequality in Portugal

Wage inequality in Portugal has been systematically around 27%. This paper describes a set of animated cartograms that show this inequality for several years. The visualization was designed for an exhibition setting, and instead of presenting the final cartograms, it shows the cartogram formation for each year as a way of reiterating the message. The model used is a modification of Dorling cartograms that visually appears as a set of contiguous amalgams of total wages earned by subregion. This aspect confers an organic tone to the artifact, as if liquids of different densities were being poured into the canvas without mixing, and depicting a tension-based behavior where amalgams of men and women push among themselves to compete for the same space.
