This example loads a CSV file from a GitHub gist using D3.js v7’s `d3.csv` method and displays metadata about the dataset, including its size in kilobytes, row count, and column count, in a styled HTML `<pre>` element. The page also embeds an SVG image directly in the markup. The code demonstrates basic asynchronous data loading and DOM text manipulation with `document.getElementById`, along with CSS styling for headers and text presentation.
