This example shows a minimal React application that loads CSS named color data from a CSV file and displays summary statistics about the dataset. The code uses D3’s `csv` utility in a React `useEffect` hook to fetch the data, then stores it in state via `useState`. The rendered output presents the file size in kilobytes, row count, and column count using `d3.csvFormat`. While loading, the interface displays a simple “Loading...” message before the statistics appear.
