{"version":"1.0","type":"rich","title":"Map of World Happiness Data","description":"A world map rendered in SVG displays nuclear explosion locations as small points on a Mercator projection. The visualization uses the World Atlas TopoJSON for land interiors and graticules, with the `geoPath` API to draw the map. Each data point is positioned via the `geoMercator` projection and includes a hover tooltip showing its latitude and longitude. The data comes from a CSV of nuclear explosions, loaded with the D3 `csv` function, and the entire chart is built with React and D3 v5.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c410fdc55a274fa2a38dc7821e3a0865?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
