This pie chart displays the total championship wins for each IPL team up to 2019, using data from a CSV file. The D3.js v5 code uses `d3.pie` to compute the arc segments, which are rendered as SVG paths with `d3.arc`. The chart is colored with a `d3.scaleOrdinal` color scale, and legends are generated manually using SVG circles and text elements. The data is loaded asynchronously via a custom `getData` function that utilizes `d3.csv`.
