This example displays a page that loads a CSV file from a GitHub gist, then calculates and displays the file size, row count, and column count. The data is fetched using D3.js v7’s `d3.csv` method, and the string summary is rendered in a styled `<pre>` element. The page also includes a decorative SVG image. The visualization is built with React and relies on D3’s CSV parsing and formatting APIs to summarize the dataset.
