{"version":"1.0","type":"rich","title":"The keeling curve dataset with D3","description":"This example displays monthly atmospheric CO2 concentrations from the Keeling Curve dataset as a line chart, with measurements in parts per million shown over time. The code loads CSV data using `d3.csv`, filters missing values, and renders the chart as SVG. It uses `d3.scaleTime` and `d3.scaleLinear` to map dates and CO2 values, `d3.line` to create the path, and `d3.axisBottom` and `d3.axisLeft` to draw axes. A loading state is shown via `d3-rosetta` state management before the data arrives.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/68a735f4889c4d8dbb353bb07d70c945?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
