This example demonstrates how to load and parse a CSV file using D3 v4 within a React application, displaying the dataset's basic statistics—file size in kilobytes, row count, and column count—in a styled HTML paragraph. The SVG background includes decorative vector shapes and icons, while the main interaction relies on `d3.csv` to fetch data from a GitHub Gist URL and log the parsed result to the console. The page uses CSS for visual formatting, with the message rendered via the DOM's `textContent`.
