This example displays a plain-text summary of a CSV dataset listing the populations of the most populous countries, based on 2018 United Nations estimates. The page prints the total row count, column count, and file size in kilobytes, followed by the first ten rows of data in a formatted JSON structure. The implementation uses D3 v7 methods `select`, `csv`, and `csvFormat` to load the data, compute its metadata, and render the output as HTML `pre` elements. Styling is provided by an external CSS file.
