{"version":"1.0","type":"rich","title":"World Happiness Scores by Country","description":"This example visualizes global nuclear explosion data on a world map, with each detonation represented by a colored circle whose size corresponds to yield magnitude. The map uses D3’s geoNaturalEarth1 projection and geoPath to render landmasses, graticules, and country borders from TopoJSON data. A scaleOrdinal color scale assigns distinct hues per country, while a scaleSqrt maps yield values to circle radii. React manages hover interactions, dimming non-hovered points via opacity and filtering the top layer to highlight selected countries. The legend, built with React components, supports interactive filtering of the dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4bf0925d64246f0bffe3e36d6545217?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
