Adding transition animation to scatters
In Scatter visuals, CDP Data Visualization implements a powerful feature: transition animation.
In the World Life Expectancy dataset, we use the time as the transition 'axis' to show how GDP per capita, life expectancy, and population size changes over time, from year 1990 through year 2010.
For this visual, we will start with the existing visual World Population - Scatter with Size, which is developed in Adding size to scatters.
While we can see the data for individual countries more clearly, it is often useful to contrast well-defined logical segments of data.
Let us next look at comparing and contrasting GDP per capita and life expectancy for different UN Regions in Adding Trellises to Scatter Visuals.
