Each circle’s x-position maps to GDP, y-position to population, and radius to life expectancy, with country labels and hover highlighting. The SVG chart uses D3 v7 with `scaleLinear`, `d3.csv`, and `axisBottom`/`axisLeft`, reading data from an embedded CSV file. The code styles circles with the `.bubble` class and applies opacity changes on mouseover and mouseout events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/acf8110c14844cdbae02250ff2e1a7df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
