{"version":"1.0","type":"rich","title":"country, year, population, vaccinated, percent_vaccinated","description":"A scatter plot shows the relationship between varicella vaccination rates and cases per capita across five South American countries in 2020, with point size encoding population. The visualization uses D3 scales (`scaleLinear`, `scaleSqrt`, `scaleOrdinal`) and axes (`axisBottom`, `axisLeft`) to render the chart. A legend with hover interactions highlights individual countries by fading non-hovered points. The code loads embedded data rather than an external source and applies a custom theme with color assignments per country.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9d25021fa1f4167a838e11f93303ede?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
