  The distribution of household income is a central concern of modern economic
policy due to its strong influence on life quality. Yet, non-expert audiences
are unaware of the relationship between these two factors. To effectively
communicate the effect of income inequality on the quality of life and among
the strata, we have designed a novel technique for visualizing income
distribution and inequality over time by using the U.S. household income
microdata from the Current Population Survey. The result is a striking dynamic
animation of income distribution over time, drawing public attention and
further investigating economic inequality. Detailed implementation of this
project is available at https://github.com/sangttruong/incomevis.
