We adapted the chord diagram plot to visualize Brazil’s interstate migration during 1991–2010. The arrowheads were added to present the direction of the flows. This method allows us to show the complete migration flows between 26 states and the Federal District in Brazil, including the direction and volume of the flows. The spatial component was also clearly depicted in the plot using four color palates representing five regions in Brazil (i.e. North, Northeast, Southeast, South and Midwest) and arranging the 27 states in approximate geographical order. Besides that, we will extend the chord diagram plot to describe the stocks of interstate migration in Brazil in 2010 in comparison to the bilateral flows presented.
