This example loads a student-to-teacher ratio dataset from a CSV file and displays summary statistics about the data, including its size in kilobytes, row count, and column count. The visualization uses the D3.js library (v5) to fetch and parse the CSV via `d3.csv`, then formats the results using `d3.csvFormat`. A large `<pre>` element shows the computed metrics in text form. The dataset, sourced from Tidy Tuesday, contains country, year, educational level, and ratio fields, though the current code only reports dataset dimensions rather than rendering charts or graphs.
