This visualization summarizes a student sports dataset, showing a bar chart of team counts alongside text statistics for total students, unique subjects, and the top team. The code uses `d3.csv` with `d3.autoType` to fetch and parse the data, then `d3.rollups` with `d3.descending` to compute team frequencies. An SVG bar chart is rendered using `d3.scaleBand` and `d3.scaleLinear`, with axes drawn via `d3.axisBottom` and `d3.axisLeft`. The page structure and styling come from the accompanying `index.html`, `styles.css`, and `script.js` files.
