{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"Two synchronized world maps animate COVID-19 new cases per 100,000 people and vaccination rates over time, using sequential red and green color scales to encode values. Each map includes a play button and slider to scrub through dated records, with the choropleth paths colored from CSV data. The visualization uses D3.js version 3 with `d3.geoNaturalEarth2`, `d3.geo.path` for map projection, TopoJSON from the world-atlas package, and ISO country code mappings to join the data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2397116e05a4443abd39d270ff89911?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
