Each bubble is colored by continent using a d3.scaleOrdinal with the d3.schemeCategory10 palette. The code employs d3.scaleLinear for both axes and d3.scaleSqrt for the radius. SVG rendering displays the circles with a predefined margin and stroke, with data embedded directly in the script.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c814b61f6c841f4a42cdeb0670e243c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
