This example displays the first record from the US Airline Traffic Dataset as pretty-printed JSON in a `<pre>` element. The code loads the CSV file, parses all numeric fields by removing commas, constructs a UTC `Date` object, and adds a formatted `YearMonth` string, then exports the processed data and renders the first object’s contents. It relies on a default import of `data.csv` and uses no third-party visualization libraries, focusing solely on data cleaning and raw output.
