A new and exciting possibility of representing time-series data. Instead of plotting time on one of the axis, two different data sets were plotted on each axis. Hit the 'Play' button and see this become animated. The "Bubbles" representing countries moves, changes in size and color as time goes forward. This is an interactive application. Assigning which variables are displayed on which dimension radically changes the picture. This allows you to look at several metrics at once, revealing meaningful patterns and trends that would be hidden in simpler charts or spreadsheets.
This application is also offered at regional and national scale.
