{"version":"1.0","type":"rich","title":"Untitled","description":"A bubble chart displays countries as circles positioned by GDP per capita (x-axis) and life expectancy (y-axis), with circle size encoding population. Each bubble is colored by continent, drawn as SVG circles using `d3.forceSimulation` with custom forces for positioning. The code loads data from a JSON array and uses `d3-scale-chromatic` for categorical color mapping. Hovering a bubble changes its stroke from white to black via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f54adbd76be94c12b93237c0b43dde6c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
