This example demonstrates how to load and parse CSV data using D3.js, displaying the file size, row count, and column count in a styled HTML page. The page includes a custom SVG illustration and fetches a remote CSV file from a GitHub gist via the `d3.csv` method. The code counts the data length, formats the raw CSV text to estimate its size in kilobytes, and inserts the results into a `<pre>` element using standard DOM manipulation. The visualization is built with React and rendered as SVG, with CSS styling applied to the message container and heading.
