{"version":"1.0","type":"rich","title":"Interactive COVID-19 Dashboard Bar and Map","description":"This interactive dashboard visualizes COVID-19 vaccination data across U.S. states, combining a bar chart of daily doses for a selected state with a map showing vaccination rates nationwide. Users brush the bar chart to choose a date, and the map updates to display doughnut charts at state centroids, with arcs indicating the percentage of residents fully vaccinated and doses used. The visualization uses React, D3 v6 (including `d3.forceSimulation`, `d3.geoPath`, `d3.brushX`, and `d3.scaleSqrt`), and SVG rendering. Data comes from US Vaccination Data by State/Territory, with map shapes from the us-atlas TopoJSON.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/81ecde3d496f4bc6b819602ad836c34c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
