A stacked bar chart examines Asian American quality-of-life ratings across ethnic groups, using survey data from a CSV file. The chart shows the distribution of “Poor,” “Fair,” “Good,” and “Excellent” responses for each ethnicity, with bar segments colored by rating and tooltips revealing counts. Built with D3 v7, it uses `d3.stack` to aggregate counts, `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `scaleOrdinal` for colors, rendering as SVG rectangles. Hover interactions adjust opacity to highlight segments.
