{"version":"1.0","type":"rich","title":"Fork of COVID-19 Map (Positive Cases)","description":"This choropleth map displays the relative number of COVID-19 cases per U.S. state using a log-transformed scale of seven-day average positive test results, colored with d3.scaleThreshold and schemeOrRd. Hovering reveals a tooltip with state-level metrics including deaths, tests, and positivity rates. Built with React and D3 v6, the visualization uses d3.geoPath with a geoAlbersUsa projection, TopoJSON for state boundaries, and a d3.Delaunay-based Voronoi overlay for efficient mouse interaction over irregular shapes. The accompanying color legend is rendered using d3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b17f4d4314d24cc1838749fed8e77dcf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
