This visualization uses a stacked horizontal bar chart to show the percentage of bachelor's degrees earned by Asian, Black, and White students across U.S. states. The code processes the provided data to calculate proportions and uses D3.js (v7) to render the chart as an SVG. It employs `d3.stack()` to create the stacked series, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.scaleOrdinal` with a color range to distinguish the three racial groups. A legend and axis labels are added for clarity.
