This stacked bar chart shows the proportion of students enrolled in five different programs—Engineering, Computer Science, Business, Liberal Arts, and Health Sciences—across five universities, with each bar segmented by program and colored via a categorical scale. The visualization uses D3 v7’s `d3.stack()` to compute the stacked segments, `d3.scaleBand()` for the university categories, and `d3.scaleLinear()` for the percentage axis. Hovering over a segment triggers a tooltip displaying the exact percentage for that program at that university, using D3 event handlers. Data comes from an embedded `data.csv` file, rendered as SVG with custom styles from `styles.css`.
