This stacked bar chart visualizes five days of fruit quantities, with three series (apricots, blueberries, cherries) shown as horizontal segments per day. The chart uses D3 v7’s `d3.stack()` to compute the cumulative y-values for each series, then binds the stacked data to SVG `rect` elements. Series colors are applied via a static array, and day labels are rendered as SVG text. The visualization demonstrates stacking without axes, focusing on the proportional differences between fruit categories across the week.
