This visualization displays the percentage of bachelor's degrees earned by Asian, Black, and White residents across U.S. states, with each state represented as a horizontal stacked bar showing the proportional share of each ethnic group. The chart uses d3.stack() to compute the stacked series, d3.scaleBand() for the categorical state axis, and d3.scaleLinear() for the percentage axis. Rendering is done via SVG rectangles within a D3 v7 selection, styled with a color ordinal scale and annotated with axes and a legend.
