This example summarizes a CSV dataset of the most populous countries in 2018, sourced from the United Nations World Population Prospects. It displays the total row count, column count, and file size in kilobytes, followed by a JSON-formatted preview of the first ten rows. The visualization uses d3.csv to load the data and d3.csvFormat to compute file size, rendering the summary as styled text elements in a black-and-green terminal aesthetic. Data is presented as simple text output rather than a chart.
