{"version":"1.0","type":"rich","title":"keeling dataset with D3","description":"This visualization displays monthly CO2 concentration measurements from the Keeling dataset as a smooth line chart, with years on the x-axis and CO2 concentration in parts per million on the y-axis. It uses d3.csv for data loading, d3.scaleLinear for axis scaling, and d3.line with curveMonotoneX to draw the trend. The SVG rendering includes axis labels, a steelblue stroke, and a loading state. Data is sourced from a GitHub gist containing the Mauna Loa measurements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76fc337eda3d400e9c217e5bfc10ed20?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
