{"version":"1.0","type":"rich","title":"Fork of COVID-19 Map (Positive Cases)","description":"This choropleth map of the United States displays the seven-day average of positive COVID-19 test cases per state, using a logarithmic color scale from `d3.scaleThreshold` with a `d3.schemeOrRd` color range. State boundaries are drawn with `d3.geoPath` and the `geoAlbersUsa` projection. The visualization includes an interactive Voronoi overlay built with `d3.Delaunay`, which triggers hover states, while a custom `colorLegend` shows the threshold values. User-provided CSV data supplies the values, which are mapped to each state’s fill color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0ec722f3edca4dff8d1770b601f031be?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
