This example displays a plain-text summary of a CSV dataset about population estimates from the United Nations’ World Population Prospects 2017. It uses d3.csv to load the data, then d3.csvFormat and the data’s length to calculate and print the total row count, column count, and file size in kilobytes, followed by a JSON representation of the first ten rows. The output is rendered in a green monospace font on a black background, mimicking a terminal interface.
