{"version":"1.0","type":"rich","title":"Fork of Activity7_Question2_5","description":"This area chart displays COVID-19 confirmed cases in the US over time, sourced from a combined time-series CSV dataset. The visualization uses D3 v7's `d3.csv` loader, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.area` to generate the filled path. Axes are rendered with `d3.axisBottom` and `d3.axisLeft`, while data is aggregated by date via `d3.rollup`. The chart includes labeled axes and a title, with styling applied through CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2162163327004fde85f4517e512e2711?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
