This pie chart displays the distribution of carbon emissions across different states in the USA, with each slice representing a state’s total emissions in thousand tonnes. The visualization uses D3 v5’s `pie` and `arc` generators to create the SVG segments, while `scaleOrdinal` assigns colors to each state. Legends are positioned manually alongside the chart, and data is loaded asynchronously from a CSV file via a custom `getData` function using D3’s `csv` method.
