This example demonstrates loading and parsing CSV data using D3 v5 within a React framework. It fetches a dataset of CSS named colors from a GitHub gist and renders the raw content into a large HTML `<pre>` element. The code uses the Fetch API to retrieve the CSV file, with D3’s parsing functions handling the comma-separated values. The visualization focuses on the data-loading workflow, as the fetched text is displayed without further transformation or charting, highlighting the initial step of bringing external tabular data into a web application.
