{"version":"1.0","type":"rich","title":"Bubble Chart","description":"This bubble chart maps countries’ birth rates to the x-axis and life expectancy to the y-axis, with bubble size scaled by population. The visualization uses D3 v6’s `scaleLinear` for positioning and `scaleSqrt` for radius, while an ordinal color scale distinguishes countries. Each circle is rendered as an SVG element with a dark blue text label, and the chart includes standard `axisBottom` and `axisLeft` axes. The sample dataset is embedded directly in the code, and the visualization is presented in a 700x450 pixel container.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c8ca831ef1e467ab3f37b87b947711c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
