This example demonstrates the basics of loading and parsing CSV data with D3.js. It displays a summary message showing the number of rows, columns, and file size in kilobytes of a remote CSV file containing CSS named colours. The code uses `d3.csv()` to fetch and parse the data asynchronously, then accesses the resulting object’s `length` and `columns` properties to create the summary. The parsed data is formatted back with `d3.csvFormat()` to calculate the file size, and the message is rendered in a large `<pre>` element.
