This visualization shows the 2023 U.S. utility-scale electricity generation mix as a pie chart, with each slice representing an energy source’s share of total generation. D3 v7’s `d3.pie` and `d3.arc` generate the slices, while `d3.scaleOrdinal` assigns colors from the Tableau10 scheme. Percentage labels appear on slices exceeding three percent. A scrollable legend, sorted alphabetically, lists each category with its exact share. Data is loaded from a CSV via `d3.csv`, and the chart is rendered as SVG with a responsive `viewBox`.
