This pie chart visualizes the top 10 car production countries in the world for 2019, sourced from a CSV file loaded via `d3.csv`. The visualization shows each country's total production value as a slice of the pie, with a legend on the right listing country names and their corresponding values in thousands. Using D3 v5, the chart is rendered as an SVG with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to define the segments and colors, while `d3.format` displays the values. The code appends paths and legend elements to the SVG, positioning the pie at coordinates (250,220) with a 175-pixel outer radius.
