This example demonstrates how to load and parse CSV data in a web application, displaying a summary of the dataset’s size in kilobytes, row count, and column count. The code uses the D3.js library (v5) to fetch a CSV file containing CSS named colors from a GitHub gist and then parse it with `d3.csv`, while leveraging the Promise-based `.then()` method for asynchronous handling. The resulting message is rendered inside an HTML `<pre>` element. The implementation also includes commented-out alternatives using `fetch`, `async`/`await`, and `d3.csvParse`.
