{"version":"1.0","type":"rich","title":"Activity_Task_4","description":"This bubble chart maps GDP against life expectancy for various countries, with bubble size reflecting population and color indicating country. The visualization uses D3 v6 to render an SVG, employing `d3.scaleLinear` for both axes and `d3.scaleSqrt` for bubble radii. Data is loaded from a CSV file via `d3.csv`, which also populates a manual legend. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and all chart elements—including the title and axis labels—are appended as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f48e8cd7a7874e799498126c0b145b68?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
