This example shows the size of a CSS named colors dataset by displaying its byte count, row count, and column count as large text. It loads the data from a local CSV file using the `csv` function from D3 v5, then uses React hooks `useState` and `useEffect` to manage the asynchronous data loading and trigger a re-render. The `message` function computes the statistics with `d3.csvFormat` and `data.columns`, displaying a loading message until the data arrives. The visualization relies on React 16.9 and D3 for data parsing and formatting.
