This example demonstrates a minimalist data-loading interface that displays summary statistics about a CSV dataset, including its file size in kilobytes, row count, and column count. Built with React and D3 v7, it uses the `useState` and `useEffect` hooks to asynchronously fetch and store data via `d3.csv`. The imported `message` function formats the statistics, which are rendered as text inside a `<pre>` element within a styled dark-themed SVG container.
