This page demonstrates how to load and parse CSV data from a remote URL using D3.js version 7. After fetching the data, it displays a summary message containing the file size in kilobytes, row count, and column count in a large text element. The example also shows an SVG map image. The code uses the `d3.csv()` method to fetch the file and `d3.csvFormat()` to calculate its size, with the results rendered inside a `<pre>` tag.
