{"version":"1.0","type":"rich","title":"Fork of World Happiness Graph","description":"This example links a choropleth world map with a scatter plot to explore the relationship between happiness scores (the \"Ladder score\") and GDP per capita. The map uses a color gradient to encode happiness, while the scatter plot, color-coded by continent, reveals a positive correlation. Hovering over a map country highlights its corresponding dot and triggers a tooltip with details. Built with D3 v6, it uses `d3.geoEqualEarth` and `d3.geoPath` for the map, `d3.scaleLinear` and `d3.scaleLog` for scales, and `d3.select` to build the SVGs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/214c538d883a490086637c07c4b937e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
