This example demonstrates the process of loading and parsing a CSV file with D3.js, displaying a summary of the dataset in a large red text block. The visualization shows the number of rows, columns, and file size in kilobytes of the CSS named colors dataset fetched from a GitHub gist. The code uses d3.csv() to asynchronously load and parse the data, then d3.csvFormat() to calculate the file size. An alternative commented-out approach using fetch() and d3.csvParse() is also provided.
