This visualization demonstrates the Keeling Curve dataset, showing atmospheric CO2 concentrations measured at Mauna Loa Observatory since 1958. The code parses the CSV data and converts missing values (marked as -99.99) to NaN, while also adjusting dates to Hawaii time using the Date API with UTC parsing. The main export function displays the first data row as formatted JSON in a pre element, utilizing the browser's native JSON.stringify for presentation.
