{"version":"1.0","type":"rich","title":"Fork of Fork by Yizhan Niu","description":"A dashboard visualizes state-level COVID-19 vaccination data, showing daily doses administered on a U.S. map and a corresponding bar chart for a selected state. Users choose a state from a dropdown menu and brush the lower bar chart to filter dates, updating the map’s circles. Built with D3 v6 and React, it uses `d3.geoPath` for state outlines, `d3.forceSimulation` for non-overlapping circles, and `d3.brushX` for date selection. Data comes from US Vaccination by State/Territory.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f08ec7aa6bfd4fa18356b81e29400ad3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
