A forked interactive stacked bar chart displays job titles against their aggregated populations from 1980 and 2023, sourced from a merged dataset. The visualization uses D3.js version 6, rendering SVG rectangles. Color-coded bars for each year are grouped by job type, with tooltips showing the exact population values on hover. The chart employs D3's scaleBand for the x-axis and scaleLinear for the y-axis, with population data summed via d3.sum.
