{"version":"1.0","type":"rich","title":"US Daily COVID-19 Vaccination Dashboard with Doughnuts","description":"This dashboard visualizes US COVID-19 vaccination data with an interactive map and bar chart. The map displays doughnut charts for each state, where blue arcs show the percentage of fully vaccinated residents and green arcs show vaccine doses used. Users can select a state from a dropdown to view its daily vaccination counts, and brushing the bar chart updates the map’s displayed date. The visualization uses D3.js force simulation for non-overlapping circles, geoPath for map rendering, and React for state management. Data comes from a gist containing US vaccination statistics by state.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7b144d21b3634dbab08c6721cd402d2f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
