This example demonstrates loading and parsing CSV data using D3.js v5 within a React framework. It fetches a CSS Named Colors dataset from a GitHub gist and processes it to display the file size, row count, and column count in a large text element. The code includes commented-out implementations using `d3.csv`, `d3.json` with promises, and modern `fetch` with async/await syntax, highlighting different approaches to handle asynchronous data loading.
