This example displays the size and structure of a CSS Named Colors CSV dataset in a large text block. It uses d3.csv to fetch and parse the data, then computes and presents the file size in kilobytes, the total row count, and the number of columns. The visualization also includes commented code showing alternates using fetch with async/await and d3.csvParse, demonstrating different approaches to loading CSV data in D3 v5 within a React framework.
