This visualization displays the raw dataset of IMDb’s 250 worst-rated movies as a formatted JSON preview. It loads a CSV file with movie attributes like title, year, duration, genre, and rating using `fetch` and parses it with `d3.csvParse`. The current state is managed via a `setState` callback, and D3’s `select` and `join` methods render the parsed data into a `<pre>` element for inspection. The example demonstrates a minimal data-loading pattern with D3 v7, showing the transition from undefined state to a structured array of movie objects.
