This example demonstrates the basics of loading and parsing comma-separated values in the browser. It fetches a CSV file containing CSS named colors from a remote URL and uses d3.csv to parse the data, then displays a text summary of the file’s size in kilobytes, row count, and column count. The code also includes commented-out alternatives using the Fetch API with async/await and d3.csvParse, as well as nested promise callbacks, to illustrate different parsing approaches. The output is rendered as plain text inside a large <pre> element.
