{"version":"1.0","type":"rich","title":"Keeling curve with D3","description":"The chart displays atmospheric CO2 concentrations measured at Mauna Loa, Hawaii, from 1958 onward. It uses a line and scatter plot of monthly measurements, showing an overall upward trend. The visualization is built with D3 version 7, using `d3.scaleTime` and `d3.scaleLinear` to map dates and CO2 values. Data is manually parsed from a CSV file, filtering out missing values, and points are colored by station (blue for MLO, red for others).","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7c1f8b2aee72407386e84890d6f5bf51?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
