This page displays metadata about a GoodReads customer dataset, including its size in kilobytes, row count, and column count. The visualization loads a CSV file from a GitHub gist using `d3.csv` and processes the data with `d3.csvFormat` to calculate the file size. It then updates the text content of a `<pre>` element via the DOM API. The page is styled with simple CSS, using coral backgrounds and centered headings, and runs on React with D3 v7.
