A pie chart displays the renewable energy share percentages for various countries in 2023, using colored slices with country labels and a legend that lists each country alongside its exact percentage value. The chart is built with D3 v7, loading CSV data from a GitHub gist, and renders as SVG. It applies d3.pie and d3.arc to compute the slice geometry, while d3.scaleOrdinal with the Tableau10 color scheme provides categorical colors for each country.
