This example displays a text-based summary of a CSV dataset containing United Nations 2018 population estimates for the ten most populous countries. It shows the row count, column count, and file size in kilobytes, followed by the first ten data rows formatted as JSON. The visualization uses D3 v5’s `csv` and `csvFormat` functions to load and measure the data, then appends `<pre>` elements to the DOM to render the summary and raw data output.
