This pie chart visualizes fruit sales data, displaying the proportional share of each fruit category as a labeled slice with a corresponding legend. The chart is rendered as an SVG using D3 version 7, with the pie generator `d3.pie()` and arc generator `d3.arc()` calculating angular extents and centroids for labels. Data is loaded via `d3.csv` from a remote Gist, and the color scale `d3.scaleOrdinal` with `d3.schemeSet2` assigns categorical colors. The legend is built using `d3.select` and `enter()`, while sales values are cast to numeric type before creating the pie layout.
