This example presents a terminal-style summary of graduate student earnings and labor force data from FiveThirtyEight’s “Economic Guide to Picking a College Major.” The visualization displays the dataset’s row and column counts, its size in kilobytes, and the first ten rows as formatted JSON. Using d3.csv to load the data and d3.csvFormat to calculate size, it renders the output as ASCII text in a black page with green monospace styling. The code relies on D3 v5’s selection, CSV parsing, and formatting utilities.
