{"version":"1.0","type":"rich","title":"Let's make a BarChart 2","description":"This example displays a time-series bar chart of daily COVID-19 case counts from August to September 2020. The bars are animated into view, and hovering over a bar changes its opacity and reveals a tooltip. The visualization uses D3 v6 to parse the CSV data, map dates to the x-axis via `d3.scaleTime` and case numbers to the y-axis with `d3.scaleLinear`, and render the bars as SVG rectangles. The axes are generated using `d3.axisLeft` and `d3.axisBottom`, while mouse interactions rely on D3’s selection and transition APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95c54334f01c4279bcd5a9086fbbc3ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
