This example demonstrates the basics of loading and parsing CSV data, displaying the file size, row count, and column count of a dataset of CSS named colors. It uses D3 v5’s `d3.csv()` method, which returns a promise, to fetch the data from a GitHub gist. The code then formats the statistics using `d3.csvFormat()` and `data.columns`, injecting the results into an HTML `<pre>` element. Commented-out alternatives illustrate the same process using `fetch()` with async/await and `d3.csvParse()`.
