{"version":"1.0","type":"rich","title":"COVID-19 Map (Positive Cases)","description":"This interactive map of the United States visualizes COVID-19 positive cases by state, with fill colors encoding the log-transformed seven-day average of positive tests, ranging from 5 to 11 on a threshold color scale. A voronoi overlay, built with `d3.Delaunay.from` and `voronoi.renderCell`, enables hover interactions, while each state path (rendered with `d3.geoPath` and `geoAlbersUsa`) displays a tooltip with additional metrics including death toll, tests, and positivity rate. The visualization also includes a threshold color legend and uses React for managing the overlay component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2f2bc6c6289a4b47bae1bd37513b2e01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
