Loading and Parsing CSV Data
This example uses D3 to load a remote CSV file containing CSS named colors and display a summary of its content. It employs the `d3.csv` function to fetch and parse the data asynchronously, then calculates the file size in kilobytes, the number of data rows, and the column count. This information is rendered as large text inside a `<pre>` element, with the message constructed using `d3.csvFormat` to measure the formatted data length. The result demonstrates both the loading process and the resulting data structure.
