This pie chart visualizes the top 10 countries by number of births in 2020, with each slice’s size proportional to reported deaths and labeled with values in thousands. The chart uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate SVG paths and text labels, with a legend positioned to the right. Data is loaded from a CSV file via `d3.csv` from a GitHub gist, and each segment is colored using a predefined palette of ten colors.
