{"version":"1.0","type":"rich","title":"Map of Nuclear Explosions with Time Histogram","description":"This interactive visualization combines a geographic map of U.S. nuclear explosion sites with a time histogram. The map displays each detonation as a circle, with color indicating the responsible country and a legend that filters points on hover. A separate bar chart below shows the total number of nuclear events per year. Built with React and D3 v5, the visualization uses `geoAlbers` projection via `d3.geoPath`, scales from `d3.scaleOrdinal`, and a histogram created with `d3.histogram`. Data comes from the Nuclear Explosions CSV dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d166d9ef7f774cc795980a23684beb18?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
