{"version":"1.0","type":"rich","title":"Fork of Fork by Yizhan Niu","description":"This dashboard visualizes COVID-19 vaccination doses administered across the United States, combining a choropleth-style map with a linked bar chart. The map displays circles representing vaccination numbers for each state as of a selected date, while the lower bar chart shows the daily doses for a state selected via a dropdown menu. Users can brush the bar chart to choose a date range, updating the map accordingly. The visualization is built with React and D3 v6, using `d3.geoPath` for the map, `d3.forceSimulation` for circle packing, and `d3.brushX` for brushing interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1fc25d036670469cacd70dc8819db28e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
