This example presents a pie chart visualizing COVID-19 death counts for the top 10 countries, with each slice labeled in thousands and accompanied by a legend listing countries and their corresponding values. The chart reads data from a CSV file hosted on GitHub, processed using `d3.csv`, and renders with SVG via `d3.pie()` and `d3.arc()`. Slices are colored using `d3.scaleOrdinal` with a fixed palette, and labels are positioned using arc centroids. The visualization is built with D3 v5 within a React framework.
