{"version":"1.0","type":"rich","title":"Keeling Curve Data","description":"This example displays the raw JSON structure of the first row from the Keeling Curve dataset, which records atmospheric CO₂ concentrations at Mauna Loa. The code imports the CSV data, converts date fields to JavaScript `Date` objects in UTC, and replaces the sentinel value of -99.99 with `NaN` to handle missing measurements. A simple `<pre>` element renders the formatted JSON output. The dataset originates from the Scripps CO2 Program.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5df089b26f34462595218d915a7b6f94?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
