This pie chart displays the percentage of sales for different items, with a legend positioned to the right showing each item’s name and corresponding value. The chart is built with D3 v5, using `d3.pie` and `d3.arc` to generate the segments, `d3.scaleOrdinal` for color mapping, and `d3.csv` to load the dataset from a GitHub gist. The visualization renders as SVG, with section labels and legend text styled via CSS.
