This example demonstrates how to load and parse a CSV data file using D3.js, displaying the file’s size, row count, and column count in a large text block on a web page. The code uses the `d3.csv` method to fetch data from a GitHub Gist URL, then formats the data with `d3.csvFormat` to calculate its size. The page also includes an inline SVG image and applies simple CSS styling, with the visualization rendered in an HTML pre element. The approach is minimal, focusing on data loading and basic metadata reporting rather than complex charting.
