This example demonstrates the initial loading state of a gin review dataset, first displaying a JSON preview of the raw data before fetching and parsing the CSV file. The visualization uses D3's `select` to bind to the container, `join` to manage the `<pre>` element, and `csvParse` to transform the tabular data into JavaScript objects. The code explicitly handles three states—undefined, 'LOADING', and loaded data—to show the transition from a blank screen to the final structured dataset. The dataset itself originates from a Kaggle gin review collection, containing fields such as price, ABV, score, and tasting notes.
