This visualization displays university rankings from a CSV dataset as an interactive stacked bar chart. Users can sort universities by overall score or individual performance metrics, and choose ascending or descending order using dropdown menus. The chart renders with D3.js v4, using `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `scaleOrdinal` for color mapping. The bars stack five score components—teaching, research, citations, industry income, and international outlook—using D3's stack API, with SVG rendering for the final output.
