{"version":"1.0","type":"rich","title":"Activity test","description":"This bubble chart visualizes the correlation between average life expectancy, population, and GDP per capita for six countries using a CSV dataset. Each circle’s position maps to life expectancy and population on the x and y axes, while its radius encodes GDP per capita and its color distinguishes countries via a `d3.scaleOrdinal` with interpolated turbo colors. Interactive tooltips appear on hover using mouse events. A legend includes size reference circles and color swatches, all rendered with SVG in D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a38253133374190aca31a3282a56538?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
