This example demonstrates how to load and parse CSV data using D3’s `csv` function within a React component. It fetches a dataset of CSS named colors, then displays a summary of the parsed data—including its size in kilobytes, row count, and column count—as plain text. The code uses React’s `useState` and `useEffect` hooks to manage asynchronous data loading, while D3 v5’s `d3.csvFormat` computes the file size. The visualization relies on React for rendering and D3 for data parsing and formatting.
