{"version":"1.0","type":"rich","title":"trying pie Covid-19 confirmed cases","description":"This interactive visualization shows global COVID-19 confirmed cases per million people using a geographic map with colored regions and proportional circle markers overlaid on OpenStreetMap tiles. The map uses D3 v7 to process COVID-19 data from the v3 API and world GeoJSON from the World Atlas, applying a sequential color scale with the YlOrRd interpolator to represent case intensity. A leaflet legend displays quantile-based color ranges, while hover interactions reveal detailed country statistics in an information control. The visualization combines Leaflet's slippy map functionality with D3's data manipulation and color scaling capabilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6e18872fb2f4e1296e13f9a2a8eeac9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
