This example demonstrates the process of fetching and parsing a CSV file using D3.js version 6. It loads a small genealogical dataset from `data.csv` containing name and parent columns, then logs the parsed data structure to the browser console. The visualization uses `d3.csvParse` to convert the raw CSV text into an array of JavaScript objects, showing how column headers become object properties. The page itself is a minimal HTML document with a centered, large-font body, though no visual output is rendered—the focus is purely on data loading and console inspection through the D3 library.
