{"version":"1.0","type":"rich","title":"Population Bubble Chart","description":"This example visualizes population data for five countries as a bubble chart, mapping birth rate to the x-axis, life expectancy to the y-axis, and population to the size of each circle. Drawn as SVG circles with country labels, the chart also includes axes. The code uses D3 v6 scales (`d3.scaleLinear`, `d3.scaleSqrt`, `d3.scaleOrdinal`) with `d3.schemeCategory10` for colors and `d3.axisBottom` and `d3.axisLeft` to render the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/64376a63b96749a2ab96282f83a67b0a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
