This example displays the first record of the Diabetes Self-Management dataset as a formatted JSON object in a large monospace font. The code parses a CSV file, converting age and year to numbers and transforming diabetes and heart disease statuses into booleans. It uses the `JSON.stringify` method to serialize the data, which is then inserted into the container's innerHTML within a `<pre>` tag. The visualization provides a raw data preview, highlighting the dataset's structure and initial content.
