This example presents a minimal HTML page that displays dataset metadata for a movie review collection. The page shows a calculated summary of the CSV data, including its size in kilobytes (rounded to the nearest whole number), the number of rows, and the number of columns. The code loads data from a remote CSV file using D3 v7’s `d3.csv` method, then formats the message with `d3.csvFormat` before injecting it into a `<pre>` element. Styling is handled through a linked external CSS file, while the page structure uses standard HTML elements.
