This example demonstrates how to load external CSV data with D3 utilities and manage it through React state. It fetches a CSS named colors dataset from a GitHub gist, displaying file size, row count, and column count in a large text format. The visualization uses React’s `useState` and `useEffect` hooks to asynchronously load data via `d3.csv`, while a separate `message` module computes the statistics using `d3.csvFormat`. The interface shows a simple text summary rather than a graphical chart.
