This example displays the raw JSON of a single Lego set record, converted from the CSV data. It shows the dataset's structure, including fields like item number, theme, piece count, and regional prices. The code uses a `container.innerHTML` assignment to render a `<pre>` element, presenting the first data row formatted with `JSON.stringify`. The source is the Lego Sets Dataset, and the visualization is a simple, static data inspection rather than a chart.
