This visualization demonstrates asynchronous data loading with D3.js. It initially displays a loading state before fetching a CSV file of ramen product reviews from The Ramen Rater dataset. The code uses D3's `select` and `csvParse` functions to fetch, parse, and display the raw tabular data as a JSON object inside a `<pre>` element. The example highlights D3's data handling capabilities, with review numbers and star ratings converted to numeric values for further processing.
