This pie chart visualizes the share of total crop production for various countries, using data fetched from a CSV file. Each slice represents a country's production in million tonnes, with labels and percentage annotations for larger shares. The visualization is built with D3 v7, using `d3.pie()`, `d3.arc()`, and `d3.scaleOrdinal()` for color mapping, rendered as SVG. A legend accompanies the chart, and the code employs `d3.csv` and `d3.autoType` for data ingestion and parsing.
