It uses D3 v5 to fetch CSV data from a GitHub repository, process it with d3.csv, and render the chart as SVG paths generated by d3.pie and d3.arc. Each slice displays the death count in thousands using d3.format, while a corresponding legend with colored rectangles identifies each country. The chart employs an ordinal color scale with ten distinct colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/191840889ee74001a2fb624b8d52cd72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
