This stacked bar chart uses D3’s `d3.stack` layout to divide five categories into layered segments for apples, oranges, and grapes. Each series is rendered as SVG `rect` elements within grouped `<g>` elements, with `d3.scaleBand` positioning bars along the x-axis and `d3.scaleLinear` mapping cumulative values to heights. Colors come from `d3.schemeCategory10`, and the chart reads the static dataset directly from the script.
