This visualization summarizes student and sports data from a CSV file, displaying key statistics such as total student count, unique favorite subjects, and the top team. It presents these findings in a simple SVG bar chart that shows team counts, with axes labeled using D3's `d3.axisBottom` and `d3.axisLeft`. The data is loaded via `d3.csv` and processed using `d3.rollups` and `d3.scaleBand`, resulting in an accessible chart with a summary section and rotated x-axis labels for readability.
