This example loads a small dataset containing CSS named colors and displays a text summary of its contents. The program uses D3's `csv` utility to fetch and parse the data from a remote URL, then leverages React state to store the result. Once loaded, a custom message function computes and displays the file size in kilobytes, the row count, and the column count using `d3.csvFormat` to calculate byte length. The interface presents this information as large, simple text, with a loading message shown while the data is being fetched.
