{"version":"1.0","type":"rich","title":"taskk8_4","description":"This example displays a bubble chart comparing seven countries by their GDP, life expectancy, and population. It loads data from a JSON file and uses D3 v7 scales (d3.scaleLinear for axes, d3.scaleSqrt for bubble radius) to map GDP to the x-axis, life expectancy to the y-axis, and population to circle size. The visualization is rendered as an SVG with sky-blue, semi-transparent circles and axis labels appended directly to the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59e04abb5a2d428a972692ec02651132?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
