{"version":"1.0","type":"rich","title":"pre-class choropleth fork 5/7","description":"This example combines a choropleth map with an interactive scatter plot, visualizing country-level attributes such as life expectancy, birth rate, and urbanization rate. The map uses `d3.geoEqualEarth` and `d3.geoPath` to render geographic features, with a linear color scale encoding the selected attribute. The scatter plot supports toggling between linear and log scales for both axes via `d3.scaleLog` and `d3.scaleLinear`, with smooth transitions. Country data is parsed and matched to map features using custom name normalization in `dataProcessing.js`, all rendered in SVG using D3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3209feb6011740d984201fa4af65dbfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
