This example demonstrates how to load and display a summary of a CSV dataset using React and D3. The application fetches a list of CSS named colors from a GitHub gist, displays the file size in kilobytes, row count, and column count in a large <pre> element. It uses React’s useState and useEffect hooks to manage state, while the d3.csv function handles asynchronous data loading. A custom Message module formats the data statistics for display, showing the integration of D3 for data processing within a React component.
