This example displays a large, typographic summary of a CSV dataset’s size, presented in a browser using a `<pre>` element. It loads the CSS Named Colors data via `d3.csv` from a GitHub Gist URL, then asynchronously counts the rows, columns, and file size (in kilobytes) using `d3.csvFormat` and `Math.round`. The resulting three-line message is injected into the page with `textContent`. The visualization is minimal, focusing on the data-loading and parsing pipeline rather than graphical representation, and runs in a React environment with D3 v5.
