This example displays a summary of the CSS named colors dataset, showing its size in kilobytes, row count, and column count. It fetches the data from a remote CSV URL using D3’s `csv` utility and manages loading state with React’s `useState` and `useEffect` hooks. Once the data arrives, the `message` function formats the statistics for display, using `d3.csvFormat` to compute the byte size. The visualization is a simple text output rendered via ReactDOM, with a "Loading..." placeholder during the fetch.
