This pie chart displays the average annual income of different professions. The data is loaded from a CSV file via a Gist URL and visualized using D3 v5’s `pie` and `arc` functions to generate SVG path segments. Each slice is colored with a categorical scale (`scaleOrdinal` and `schemeCategory10`), and a legend lists each profession alongside its corresponding color swatch and formatted income value, with the title indicating the comparison of average incomes.
