{"version":"1.0","type":"rich","title":"COVID-19 US Interactive","description":"This interactive line chart displays the rolling seven-day average of COVID-19 cases in the United States over time. The visualization uses React and D3 v6, with the data sourced from the New York Times’ public COVID-19 repository. The chart plots dates on the x-axis and average cases on the y-axis, rendered as an SVG using custom `AxisBottom`, `AxisLeft`, and `Marks` components. Hovering over data points triggers a `Tooltip` showing the formatted value. The code leverages D3’s `scaleTime`, `scaleLinear`, and `csv` for data parsing and scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c13d06d120534498a45542eb6c1b8d27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
