This example displays a text-based summary of a CSV dataset containing 2018 population estimates for the ten most populous countries, sourced from the United Nations World Population Prospects. The page shows the total row count, column count, and file size in kilobytes, followed by a JSON-formatted listing of the first ten rows. The code uses d3.csv to load the data, and d3.csvFormat to calculate the data size, then appends the summary and data preview as plain text within pre elements. The visualization uses a black background with green monospace text for a terminal-like aesthetic.
