This example displays a summary of a CSV file’s contents in a large, centered text block with an aquamarine background. It loads colorhex data from a GitHub gist using `d3.csv`, then computes and presents the file size in kilobytes, the number of rows, and the number of columns. The text is rendered into a `<pre>` element via `document.getElementById` and `textContent`, with the page styled using basic CSS for headings and layout.
