This fork of an interactive stacked bar chart visualizes World University Rankings, with bars segmented by scoring criteria and universities sorted via dropdown menus. Users can toggle legend items to hide or show criteria, and hover over bars to reveal tooltips with detailed scores. The visualization is rendered as SVG using D3 v7, leveraging `d3.scaleBand`, `d3.scaleLinear`, and D3’s data-join pattern to update charts dynamically on sort or filter changes.
