This example displays the Keeling Curve dataset, showing monthly atmospheric CO₂ measurements from Mauna Loa starting in 1958. It presents the first row of the CSV as formatted JSON, highlighting the data structure including raw CO₂ values, seasonally adjusted readings, and fitted trend lines. Missing values, encoded as -99.99, are converted to NaN during preprocessing. The visualization uses ES module imports to load the CSV directly and renders the parsed object in a styled `<pre>` element.
