This example shows a plain-text summary of a dataset containing the 2018 population estimates for the ten most populous countries, sourced from the United Nations World Population Prospects. The display reports the number of rows, columns, and file size in kilobytes, followed by the first ten rows of data formatted as JSON. The program uses the D3 v5 library’s `csv` selector to load the data and `csvFormat` to compute its size, then appends the results to the page’s body as three separate `pre` elements.
