This example demonstrates how to load and parse CSV data using D3.js v7. It displays a summary of the dataset in a pre-formatted text element, showing the file size in kilobytes, row count, and column count. The code uses `d3.csv()` to asynchronously fetch a CSV file from a GitHub gist, then `d3.csvFormat()` and `data.columns` to compute the statistics. The page is styled with CSS and includes a decorative SVG house illustration.
