This is a D3.js (v5) pie chart showing the top 10 car-producing countries by total value for 2019. Each slice represents a country's production output, with a legend listing country names and their corresponding values. The chart uses `d3.pie` and `d3.arc` to compute and render the segments, while `d3.scaleOrdinal` assigns a categorical color palette. Data is loaded from a CSV gist using `d3.csv`, and the total value is formatted with `d3.format`. The visualization is rendered as SVG, with styling defined in an external CSS file.
