This pie chart displays Austin car registrations by fiscal year from 2013–2021. The visualization uses d3.pie and d3.arc to generate SVG segments, with d3.scaleOrdinal assigning colors and d3.csv loaded from a GitHub Gist. Mouseover events reveal tooltips, while a legend lists each year. The chart includes ten color-coded slices, with data aggregated from the CSV’s CARS column and rendered as static, non-animated SVG paths.
