{"version":"1.0","type":"rich","title":"COVID-19 Map (Positive Cases per 100,000 People)","description":"This map shows the number of positive COVID-19 cases per 100,000 people by U.S. state, using a blue choropleth scale with seven-day averages. A color legend explains the threshold scale, and hovering over a state reveals detailed tooltips with death tolls, test counts, and positivity rates. Built with React and D3 v6, it loads CSV data and TopoJSON state boundaries, projecting them with `d3.geoAlbersUsa` and `d3.geoPath`. A Voronoi overlay from `d3.Delaunay` enables precise hover detection across state borders.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/446751be01da4de38771e6dba04812a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
