A pie chart displays the top eight bike sales from 2014, with each slice labeled with its sales value in thousands and a legend mapping colors to bike names. The visualization is built with D3 v5 and rendered as an SVG, using the `pie`, `arc`, `scaleOrdinal`, and `select` APIs to generate the slices, centroids, and color scale. The data is loaded from a CSV hosted on GitHub, and the chart also formats numeric labels using `format('.4~g')`.
