This example displays metadata about a movie review dataset, showing the file size, row count, and column count in a styled text container. The page loads a CSV file from a GitHub gist using `d3.csv`, then calculates the file size with `d3.csvFormat` and presents the information in a `<pre>` element. The visualization uses a custom background image via CSS, with text styled through `myStyles.css`, and includes D3 v7 imported from a CDN. The data source is a customer dataset fetched from an external URL.
