This example displays key statistics about a dataset of CSS named colors, including its size in kilobytes, row count, and column count. Using React state, the application loads the data asynchronously from a remote CSV file via D3’s `csv` utility, updating the display once the data arrives. The rendered output is a large `pre` element showing a loading message before the statistics appear, computed using `d3.csvFormat` and `data.length` and `data.columns.length`.
