{"version":"1.0","type":"rich","title":"123","description":"This dashboard visualizes COVID-19 vaccination data across US states, combining a choropleth-style map with an interactive bar chart. The map uses `d3.geoAlbersUsa` projections and `d3.geoPath` to render state boundaries, with circle sizes scaled by vaccination rates via `d3.forceSimulation` and `forceCollide` to prevent overlap. The lower bar chart displays daily doses for a selected state, using `d3.brushX` to let users select a date range. Data comes from a US vaccination dataset via CSV, with React managing state for dropdown selections and map updates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c601d3a37c5943cb8adb7e9a837e9234?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
