{"version":"1.0","type":"rich","title":"yi xiao Map","description":"This visualization displays a choropleth map of the United States, coloring each state by the log-transformed seven-day average of positive COVID-19 test results. The map also uses SVG tooltips to show each state’s name, seven-day death average, and positive test average. It loads CSV data and TopoJSON geometry, projecting it with `d3.geoAlbersUsa` and drawing paths via `d3.geoPath`. The color scale is a threshold scale from `d3.scaleThreshold` using `d3.schemeOrRd`, and it includes a custom color legend built with D3 selections.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/72ddf42a934147b083a51a80db4bfec2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
