{"version":"1.0","type":"rich","title":"yi xiao Map","description":"This example shows a choropleth map of U.S. states colored by the logarithm of their seven-day average positive COVID-19 test counts, with tooltips revealing state names, death averages, and positive test averages. Built with D3 v6 and TopoJSON, it uses `d3.geoAlbersUsa` for projection, `d3.geoPath` to render state boundaries, and `d3.scaleOrdinal` with the `schemeOrRd` color scheme. Data comes from a CSV file linked in the code, and the map is rendered as SVG with hover effects that change state fill colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dce45728376e40f0b16995dfc35657cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
