{"version":"1.0","type":"rich","title":"Fork of COVID-19 Map (Positive Cases)","description":"A choropleth map of the United States shows the relative number of COVID-19 cases, with state colors mapped to the log of the 7-day average positive test count using `d3.scaleThreshold` and `schemeOrRd`. Hovering a state turns it green, and a tooltip reveals additional 7-day averages for deaths, tests, positivity rate, and per-capita positives. The map is rendered with `d3.geoPath` and `geoAlbersUsa` from TopoJSON data, while a `VoronoiOverlay` using `d3.Delaunay` enables mouse interactions. React manages the overlay component, and a custom color legend displays the threshold scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51fc844e17a0483fa5e9d0beb3a4eb16?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
