A pie chart displays the sales distribution of electronic items in 2023, with each slice labeled by category and value. The chart uses D3 v7’s `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to generate and color the SVG arcs. Data is fetched as CSV from a GitHub repository, parsed with a custom function, and rendered with a corresponding HTML legend.
