This example visualizes the top 10 countries with deaths caused by air pollution in an interactive pie chart. Each slice represents a country, with its death count labeled in thousands and a legend linking countries to their corresponding colors. The visualization uses D3 v5, specifically the `pie`, `arc`, and `scaleOrdinal` APIs, to generate the chart in an SVG canvas. Data is fetched asynchronously from a CSV file hosted on GitHub, and the accompanying code includes integration with a YouTube tutorial in the README.
