This example demonstrates the basic process of loading and parsing CSV data using D3. It displays a summary of the dataset’s size, row count, and column count in large text. The code uses the `d3.csv` method to fetch a remote CSV file containing CSS named colors from a GitHub gist, then formats the parsed data with `d3.csvFormat` to calculate its size in kilobytes. The result is rendered into a `<pre>` element using standard DOM manipulation.
