{"version":"1.0","type":"rich","title":"Choropleth for countrycolor line 126","description":"A dual-panel visualization shows the relationship between urbanization and socioeconomic indicators across countries. A choropleth map colors nations by urban population rate using a green-to-grey scale, while a scatter plot positions countries by GDP per capita against life expectancy, with point size encoding population and color distinguishing continents. The example uses D3 v6’s `d3.geoEqualEarth`, `d3.geoPath`, and `d3.scaleLinear` within a React context, rendering both SVG panels side-by-side with animated updates and a tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8c0fee2dd204535820ac6a87e994dd3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
