This pie chart displays renewable energy generation from solar photovoltaics for the top ten countries during the COVID-19 period, with each slice representing a country’s output in terawatt-hours. The chart uses d3.pie and d3.arc to compute and draw the SVG paths, while d3.scaleOrdinal with schemeCategory10 provides the slice colors. A legend lists country names and corresponding values, formatted with a custom number format. Data is loaded as CSV from a GitHub gist, sorted descending, and rendered with React integration.
