This example demonstrates loading a CSV dataset into a React application using D3 utilities. It fetches the CSS named colors dataset from a GitHub gist and displays a summary of the data, including its size in kilobytes, row count, and column count. The React state management tracks the loaded data, initially showing a "Loading..." message until the asynchronous fetch completes. The visualization uses React 16.9, D3 7.0.1, and renders the summary text as HTML.
