This interactive pie chart displays the top 10 car-producing countries in the world for 2019, using a dataset of car production figures loaded via `d3.csv`. The visualization renders as an SVG with `d3.pie` and `d3.arc` to construct the pie segments, while a legend on the right pairs country names with their respective total production values, formatted in thousands. `d3.scaleOrdinal` assigns a distinct color to each slice, and interactivity is achieved through D3's selection and data-binding APIs.
