This example demonstrates how to load and parse CSV data in a React application using D3 v5. It displays the dataset’s file size, row count, and column count in a large text block. The code uses `d3.csv` to fetch and parse the CSV from a GitHub gist containing CSS named colors, then formats the results with `d3.csvFormat` and `data.columns`. An alternative commented approach shows `fetch` with `async`/`await` and `d3.csvParse`, highlighting modern JavaScript patterns for data loading.
