The map colors nations by urban population rate, while the scatter plot plots life expectancy against GDP per capita, sized by population and colored by continent. Hovering reveals a tooltip. The code uses D3 v6 APIs including `d3.geoEqualEarth` and `d3.geoPath` for map projection, `d3.scaleLinear` for continuous color and position scales, and `d3.scaleOrdinal` for categorical continent colors, with SVG rendering and CSS-based tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76cca7afa3f5476a8b88fa96c0813bba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
