A grouped bar chart displays university ranking data, with each institution’s score broken into five stacked components (teaching, research, citations, industry income, and international outlook). Users can reorder the bars by selecting a different score metric or sorting order from dropdown menus, built with a custom `dropdownMenu` module. The visualization uses D3 v4’s `scaleBand`, `scaleLinear`, `stack`, and `axisBottom`, rendering SVG rectangles with mouseover tooltips showing school names and component scores. Data comes from a CSV file containing Times Higher Education rankings.
