This example summarizes a CSV dataset of population estimates for the most populous countries from 1970 to 2017, sourced from the United Nations World Population Prospects 2017. It uses D3 v5’s `csv` loader to parse the data, then displays the total row count, column count, and file size in kilobytes. The page also prints the first ten rows as formatted JSON, with the results styled in a terminal-like green-on-black theme via CSS.
