{"version":"1.0","type":"rich","title":"Sunburst,covid","description":"This example shows the effectiveness of a vaccination campaign through a stacked area chart that visualizes first, second, and booster dose counts over time. Built with D3 v6, the code uses `d3.stack()` to layer the three vaccine categories, `d3.area()` with `d3.curveMonotoneX` to render the stacked areas, and `d3.scaleTime()` for the time axis. The SVG rendering includes axes and a legend, with data provided as a static JavaScript array of sample entries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/18fff282b09e4b5899a537ea5926a391?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
