Individual to stacked area charts
This interactive visualization demonstrates the transition from individual tax-rate area charts to a stacked area chart, using animated, randomly generated local, state, and federal tax data from 2000 to 2019. The SVG rendering uses D3 v4’s `d3.area`, `d3.stack`, and `d3.nest` APIs to compute and draw both the individual series and their stacked aggregate, with a monotone curve applied to each area. A looping CSS dash animation on the paths creates a dynamic, flowing visual effect.
