{"version":"1.0","type":"rich","title":"Fork of COVID-19 Map (Positive Cases)","description":"This map of the United States shows the log number of positive COVID-19 cases per state, averaged over the past seven days, with darker colors indicating higher case counts. Hovering over a state highlights it in green and reveals a tooltip with additional metrics, including death toll, tests administered, and positivity rate. The visualization is built with React and D3 v6, using `d3.geoPath` with a `geoAlbersUsa` projection to render state boundaries from TopoJSON data. A threshold color scale and a custom color legend encode the case values, while a `VoronoiOverlay` component uses `d3.Delaunay` to improve hover interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce19c558a3ad4a3187e9df21af0d146a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
