{"version":"1.0","type":"rich","title":"Zoomable COVID Vaccine Map","description":"This visualization uses a map of the United States to show the percentage of each state's population fully vaccinated against COVID-19 as of September 4, 2021. The radius of each blue circle is proportional to the state's vaccination rate, with circles positioned over state centroids. The map supports zooming via the `d3.zoom` API, which updates the SVG group's transform. The code builds the map using `d3.geoAlbersUsa` and `d3.geoPath` projections, and renders circles with proportional radii using a `d3.scaleLinear` scale. Data comes from a CSV file of US vaccination statistics, while state boundaries and centroids come from US Atlas GeoJSON and a local JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac2c8792e8c7443390966deaea5f195f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
