{"version":"1.0","type":"rich","title":"Buggy US Daily COVID-19 Vaccination Dashboard with Doughnuts","description":"This dashboard visualizes US daily COVID-19 vaccination data, combining a choropleth map of US states with a bar chart for a selected state’s daily doses. The map displays doughnut charts at state centroids, where each doughnut’s arcs represent the percentage of fully vaccinated residents and doses used. Users can interact by selecting states via a dropdown, brushing the lower chart to update the map’s date, and hovering over bars for tooltips. Built with React and D3 v6, it uses `d3.geoPath`, `d3.forceSimulation`, `d3.scaleTime`, `d3.brushX`, and SVG animations. Data comes from US vaccination records by state/territory.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/197316bcd3424f2e98de60ca9985beae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
