This example demonstrates how to load and parse a CSV file with D3.js, displaying the resulting dataset’s size, row count, and column count in a styled HTML page. It uses the `d3.csv` method to fetch data from a GitHub Gist URL, then `d3.csvFormat` to calculate the data length in kilobytes. The visualization includes a decorative SVG illustration with geometric shapes, while the text output appears in a `<pre>` element. The implementation relies on D3 v7 and vanilla JavaScript within a React-compatible HTML scaffold.
